Kaspersky Windows 10 installer does not start

If you do not install Kaspersky, the problem may not be with the system. This antivirus is compatible with almost the entire Windows family: it works on 7, 8, 10, Vista and even XP. And computer resources do not affect the download process. How the utility will work depends on them.

The reasons why Kaspersky installation fails can be very different.

Finding out why Kaspersky won't load is not so easy. After all, the reasons for the failure may be different.

Method 1: Uninstall other third-party antiviruses

In most cases, if any security software is already installed on the PC, Kaspersky Antivirus will refuse to install, but sometimes this process still ends successfully, but nothing happens at startup. We advise you to check whether the device you are using has any other antivirus or its residual files.

"Pirate"

The last common reason why Kaspersky won't start is if you have pirated software. Moreover, both the operating system and the antivirus itself are taken into account. If you have downloaded and installed a pirated software, you don’t need to be surprised when it refuses to work. After all, this is a fairly common occurrence that can be corrected by reinstalling the software.

But if you have a pirated operating system, you won’t be able to easily launch a Kaspersky license when it suddenly refuses to work. It is recommended to either change it to a pirated one, or install a licensed copy of Windows on your computer. There is no other option for the development of events. Which move to use is up to you to decide.

As you can see, the most common causes of our current problem can be corrected without outside help. If you doubt that you can handle it yourself, turn to professionals. Or, change your antivirus altogether. Users are often advised to abandon Kaspersky when it stops working. In principle, this is also not the worst advice, especially if you did not buy a licensed copy.

In Kaspersky Anti-Virus

The interface of the main program window has been significantly changed.
Modern animated design makes it easier to perceive information and simplifies the process of working with the program. In the main program window you can see all the necessary information about the computer’s protection status, the activity of protection components, the relevance of anti-virus databases and the license validity period. In addition, you can view recommendations for configuring component settings or other actions, and also check the efficiency of cloud technologies ( Kaspersky Security Network
).

Method 2: Check your computer for viruses

Kaspersky Antivirus is designed to fight viruses, but some of them, while on the computer, simply interfere with the correct launch or installation of this application, blocking its processes. This will most likely happen when you try to install any other anti-threat software, so you will need to resort to a more advanced method of eliminating viruses so that after they are successfully removed, nothing will interfere with the normal operation of the software. There are special tools that allow you to scan your PC for threats without first installing it into the operating system. Read more about them below.

Failed cryptographer

Studying at the academy was very different from a regular institute, Kaspersky recalls. Formation in the morning, formation in the evening, leave for the weekend. Students wear uniforms. If you don't pass the exams, you go into the regular army. The diploma contains only special disciplines instead of traditional subjects: SD1, SD2, SD3, SD4, history of the CPSU.

“It was so secret that I don’t remember anything.”

Near Zvenigorod in the summer of 1984

Nevertheless, Kaspersky had mostly positive impressions of the academy.

“I am very grateful to this educational institution; they taught me how to work there.”

But he did not turn out to be a cryptographer, but, by his own admission, he turned out to be a bad programmer.

“Guys, when they pick at my code... it’s gone, of course, but when they picked at it, they sometimes laughed.”

In 1989, Evgeny Kaspersky caught his first virus. At that time it was a non-trivial virus; it penetrated into the kernel of the MS DOS operating system and infected files. The virus was an advanced system program that periodically manifested itself by “strewing” letters on the screen. People ran with their monitors for repairs, saying “the letters are falling.” The virus crawled to Kaspersky on its own, he says. There was no Internet then. Networks were in their infancy. Computer viruses were then transmitted on floppy disks.

“It was a time when the bits were big and Microsoft was small. That’s when it all happened.”

Kaspersky then worked at the Multidisciplinary Research Institute of the USSR Ministry of Defense as a cryptographer. But this specialty did not appeal to Evgeniy, and in 1991 he decided to leave the government agency. About six months earlier, he realized that professional officer activity and catching viruses are incompatible things. In addition, he began to be published and invited to give presentations. It was then that the first versions of the antivirus program were written.

“At some point I realized that it was time to make a choice - either one or the other. Sometimes I joke about this, I say, if I hadn’t written the report then, I would be a general now, I would live in peace, I would drive the black Volga.”

Method 3: Checking for updates for Kaspersky Antivirus

The principle of this method is to manually check for updates for the installed version of Kaspersky Antivirus. It is quite possible that it is outdated and refuses to start due to conflicts with system components. Additionally, the update process will get rid of all damaged files and fix existing errors, if any are found. Kaspersky has a proprietary tool for searching for updates, and there are also alternative options, which is written in the most detailed form in the following instructions.

Three turning points

As Kaspersky Lab grew, it experienced three crises. The first happened in 1996-97 - at the moment when management levels and the director appeared. “We were terribly upset that we were no longer a small cooperative, but we already had management,” recalls the founder. The subsequent increase in the number of employees led to the next crisis. In 2001-02, the number of employees exceeded one hundred. Then middle management appeared, and the director no longer remembered the names of all his subordinates.

“Not everyone can cross this line,” says Kaspersky. — I know people who were selling their businesses at that moment. They simply could not get used to the fact that they did not know employees by first and last names. We survived it."

Then the crisis struck again. The company now has a board of directors and its structure has been updated. But she was not born right away.

“We spent quite a lot of time in heated arguments, walking in the park in front of the office. Thinking about how to properly reorganize the company so that it operates more efficiently. Not everyone was happy; we lost a couple of managers due to conflicts. But the remaining 90 remained.”

The modern structure of Kaspersky Lab resembles the structure of other global corporations: management board, business divisions. “There are different options for organization: a rigid pyramid, a matrix, different implementations. But the essence is approximately the same,” says Evgeniy.

Kaspersky no longer expects management crises: “I don’t know of other, more mature models of company organization, so maybe this was our last crisis.” But in such a dynamically changing and young industry, difficulties cannot be completely avoided. For example, a company decided to reorganize its development division. Kaspersky calls it very painful, explaining this by the innate conservatism of people.

“We didn't implement new development methods quickly enough. And I always want to try something new, do something differently, do it better. As a result, we came to the conclusion that it was necessary to reorganize the development in such a way that the latest methods for developing anti-virus software, created and patented by us, were used.”

Method 4: Update video card drivers

Updating your video card drivers is only required if, when you try to run the antivirus, an error appears on the screen with the notification “Error in graphics drivers occurred.” It reports that conflicts have arisen with the interaction of the program and graphics drivers. In this case, the user needs to check for updates independently or use one of the automatic third-party tools, having previously installed it on his computer.

Natalya convinced that the time has come

The decision to open their own company for Evgeniy Kaspersky’s group did not come suddenly. This was preceded by at least several years of thought, discussion and preparatory work.

In the 90s, Kaspersky worked 14 hours a day

“Long before opening the company, I asked my mentors whether it was necessary to create a separate company. Alexey Borisovich Remizov, head of the computer division of KAMI, told me: “Zhenya, it’s not worth it, you’ll go broke.” And, probably, somewhere in the first half of the 90s this was true. But in the end we just realized that we need to open our KAMI.” Arkady Volozh, who separated Yandex from the distribution company CompTek (CompTek), and Sergey Belousov, who separated software projects and computer sales, were in a similar situation at one time.
“Probably the only example where a company successfully develops programs and computers is Apple. A more or less successful example. IBM makes hardware, and all its attempts to make some kind of software were unsuccessful.”
Starting in 1995, KAMI got rid of its software projects. The antivirus division was the last to remain. The initiator of the decision to spin it off into an independent business was Natalya Kasperskaya, Evgeniy’s wife at that time: “She convinced us that it was time, the time had come. At that moment it was really obvious.” As a result, an anti-virus team of 15 people emerged from KAMI.
The initiator of the decision to spin it off into an independent business was Natalya Kasperskaya
There were no copyright problems with the antivirus developed within KAMI. After all, it was the 90s. The relationship, according to Evgeniy’s recollections, was not formalized “harmoniously” and was not regulated in any way in practice. Developers began registering intellectual property for the first time only in 1996.
Entering the market from scratch, without marketing budgets, a sales team, or independent work experience is practically useless. Kaspersky Lab understood this. The company could not place a box with its product on a shelf in a store, because... no one knew her. Serious partners were not going to represent its products in European retail chains.
“We, of course, dreamed of entering some networks, but these were only dreams,” recalls Evgeny Kaspersky.
But there was another option - to come out with technologies that are resold to other suppliers. It turned out to be much simpler.

Method 5: Reinstalling Kaspersky Antivirus

On the official website of the Kaspersky Antivirus developer there is only one recommendation for fixing the problem being discussed today and it is related to reinstalling the software. We decided to put this option at the last place in today's article, since it is either rarely effective, or re-installation is not required due to the influence, for example, of viruses or compatibility problems with the old build. If you have made all the recommendations mentioned above and none of them brought the desired result, first, using a special utility, completely remove Kaspersky Antivirus from the operating system, not forgetting about the residual files.

Now all that remains is to reinstall the antivirus application. We advise you to download the latest version of the software and follow the instructions for proper installation, which are in our separate manual on our website.

We have just discussed five methods for solving the problem of launching Kaspersky antivirus on a PC running Windows 10. For users who have downloaded unlicensed versions of this software and are experiencing problems launching, we recommend switching to a licensed build or looking for free software that performs exactly the same functions .

Problems with the .NET Framework

For Kaspersky to work stably on Win 10, 8 and 7, it needs the .NET Framework utility version 4.0 and higher. This program should already be on Windows. But if it functions with errors, you need to update or reinstall it.

Go to Microsoft.com.
Type "Microsoft .NET Framework" into the search bar.
In the "Downloads" section, select the latest version of the utility.
Click on the red "Download" button.

Download .NET Framework version 4.0

Run the resulting file.
Wait for the process to complete.

Check if antivirus is installed. If not, try uninstalling the Framework completely and downloading it again.

At KAMI, starting in the spring of 1991, he developed an antivirus called -V. The downside is that it should be at the top in the list of files. A few years later, Kaspersky reunited with his classmate Alexey De-Monderik, and Vadim Bogdanov joined them. The three young people wrote a new version, which included some innovative anti-virus ideas, and called it AntiViral Toolkit Pro.

“We wanted to publicize this utility as quickly as possible, even if it was for free, since it was not yet possible to sell it at that time. When I uploaded the file to some Western FTP server for testing, I made a mistake and instead of atp.zip I wrote avp.zip. So the name AVP is a typo that we didn't notice. But it took hold and took root.”

While working at KAMI, Kaspersky did free work for another antivirus company, and also wrote articles for Virus Bulletin magazine

While still an employee of KAMI, Kaspersky, as he himself admits, was hacking at another Russian antivirus company, which still exists. Evgeniy does not disclose its name. The developer filled the databases not only into his own antivirus, but also into someone else’s. The payment was for the recording.

“I already had a family and two children, three more Gavriks worked on the project,” he explains. — We had to buy new computers. There wasn't enough money."

In addition, once a month Kaspersky wrote articles in the Virus Bulletin magazine. They paid about $300 per article. It was a good fee back then. The working day of Evgeniy Kaspersky at that time lasted 14 hours a day.

Which Kaspersky is best for Windows 10?

Kaspersky has several products in its range:

Kaspersky Security Cloud is a comprehensive protection system that can be installed on 20 different devices using one key.
Kaspersky Internet Security (KIS) is a real-time protection tool for home computers and smartphones with Internet filtering technology.

Kaspersky Anti-Virus is basic anti-virus protection against Trojans, spyware, adware and most other dangerous programs. This is an older version of KIS.
Kaspersky Small Office Security is a product for small companies with up to 25 devices. Its main purpose is to protect file servers.
Kaspersky Free is a free program with a limited set of features. It has a lot of modules, but some of them are already available in the premium version.

Let everyone choose a product for themselves, but the most popular and in demand is KIS.

How to install Kaspersky on Windows 10?

To correctly install anti-virus protection, we recommend following the instructions:

Open the “Control Panel” by right-clicking (RMB) on Start.
Go to the “Windows Firewall” section.
Click on the menu option “Turn Windows Firewall on or off.”
Set the “Disable” parameters.
Press Win + i and go to the “Update and Security” section.
On the “Windows Defender” page, set the toggle switch to the “Off” position.
Download Kaspersky antivirus, here is a link to the Free version.
We launch the file, agree to the terms of use and wait for the installation to complete.
Reboot the computer.

Why doesn't Kaspersky install on Windows 10?

Sometimes Kaspersky does not install on Windows 10, and this may be due to a number of different reasons: from a system failure to a file being blocked by another system protection.

Why can't I install antivirus on Windows 10:

The previous Kaspersky was not completely removed from the system.
The OS is infected with viruses. They can block the installation of individual or all programs.
The computer did not restart after installation.
Problematic installer.
A required Windows update is not installed.
Problems with system files.

Another solution to the problem

Let's assume that none of the above helped you and Kaspersky is not installed on your computer, despite all your efforts. Then resort to another way to solve the problem, namely:

1) create another account in Windows OS,

2) restart your computer,

3) log in using your “freshly created” account,

4) install Kaspersky antivirus.

I must say that this often helps, and not only with antivirus software, but also with many other software products.

Recommendations for troubleshooting

Kaspersky won't install on Windows 10? Don't worry, we will help you overcome this difficulty.

Reboot the computer. If Kaspersky does not start on Windows 10 or its installation is blocked, you must restart the operating system.
We check that the KB3074683 update is installed on the PC. To do this, right-click on Start and select “Programs and Features.” Now go to the “View installed updates” section.
We completely remove the old version of Kaspersky. There is special software for this, Kavremover, which we can download from the official website. After launching, select the antivirus, enter the captcha and click on the “Delete” button.
Download the new distribution from the Kaspesky web portal. If you tried to install from an old file or the installer was not fully downloaded, you should replace it.
We remove viruses from the system. To do this, we can use an anti-virus scanner. Dr. will suit us. Web or similar software. We scan Windows with it and remove all viruses.
Recovering system files of the operating system. After problems with viruses or Windows components, you should use a utility that will eliminate all damage to files that are important for the operation of the OS. To do this, right-click on Start and select “Command Prompt (Administrator).” Enter sfc /scannow into the console.

Software incompatibility

Kaspersky works with different versions of Windows. But this does not mean that one installer is suitable for both 10 and XP. If you try to download an outdated antivirus on a modern system, nothing will work.

To fix the problem, download the latest version of the installer from the official Kaspersky Lab resource.
Open the site.
Go to the "Home" tab (or "Business" if you're looking for a corporate Antivirus).
Select the appropriate product in the left column.

Selecting Kaspersky version

There is a "System Requirements" section. It lists the supported operating systems.

It can be made simpler:

Hover over "Download".
Item "Distributions".
Click the desired antivirus.

Kaspersky for older systems can be found on the Internet.

How to fix an error when installing Kaspersky on Windows 10

Since this antivirus is maximally adapted to new versions of Windows, problems can arise for a very small number of reasons:

The system already has an antivirus from another manufacturer installed (the built-in Windows Defender does not count);
The system is already infected with some viruses that prevent the installation from completing normally.

The problem may also occur in older versions of Windows 10 operating systems that do not have the KB3074683 update, where Kaspersky and other antiviruses become maximally compatible.

Below we will look at common ways to fix the problem.

Option 1: Incorrect installation

You may be trying to install a second antivirus from Kaspersky. Typically, compatible versions of a product are interchangeable and installation simply upgrades to the appropriate version. But this does not always happen and antiviruses in the system begin to conflict. In this case, when installing Kaspersky, you will receive a notification that the system contains other products from the manufacturer that are interfering with the installation.

There is a possibility that you have previously installed other protection products from Kaspersky, but the installation was not completed completely or after some time you uninstalled this antivirus. However, there are still components in the system that prevent installation. In this case, you can finally get rid of them using a small program called Kavremover:

Download this product from the developer's official website. This program does not require installation on your computer, which is a plus; you only need to run the executable EXE file.
At the first launch, the OS will be scanned for the presence of other antiviruses from Kaspersky. Antiviruses from other developers may also be detected, but in this case it is not possible to remove them using this program.
In the “The following products detected” section, select the detected Kaspersky that is interfering with installation.
Next, you will need to enter a special code in the line above, which is displayed at the top of the interface. After that, click on the “Delete” button.

Expect programs to be removed. Once the process is complete, restart your computer.

Option 2: Conflict with other antiviruses

Antiviruses from other manufacturers will almost always conflict with Kaspersky. The only exception is the standard Windows Defender, which is automatically disabled when a third-party antivirus is detected in the operating system.

If the system has an antivirus from another manufacturer, then during the installation of Kaspersky you will receive a corresponding warning. The installation may complete successfully, but then the antiviruses will conflict with each other, which will lead to many problems, which is why it is not recommended to install 2 or more antiviruses on Windows.

You can remove most antiviruses in the standard way - through “Programs and Features”:

Open the “Control Panel” through a system search (magnifying glass icon or Win+S combination). Enter the name of the object you are looking for there. You can open it in another way convenient for you.
In the "View" field located in the upper right part of the window, select "Small Icons" or "Large Icons" (whichever is convenient for you).
Now in the interface, find the “Programs and Features” item. Open it.

In the list of programs, find an antivirus from another manufacturer. Select it by left-clicking and click on the “Delete” button that appears at the top.

The removal wizard for the selected antivirus will open. There you just need to confirm the deletion and wait for it to finish.

After this, restart your computer.

There is a virus in the system

Another possible reason is that the system is infected with malware. It is this that “does not allow” Kaspersky. The DrWeb utility will help you get rid of the virus. It does not need to be installed or removed. This is a portable program that is suitable for Windows of all versions (XP, 7, 8, 10).

Go to the website "drweb.ru".
Download tab.
Scroll down to the Freebies section.
Open "Dr.Web CureIt".
Download button.

Click on “Download for free”

Run the downloaded file.
Click "Scan objects".
Check all the checkboxes.
Click on “Run scan”.
It will take some time.
The program will display a list of suspicious data. The "Let" column will contain folders. You can choose which files to delete. If you know for sure that the object is safe, select "Skip".

It is better to carry out the check in safe mode. To enter it, press the F8 key when you turn on the computer. Options for starting the system will be offered. This way the virus will not be able to “hide”.
