Windows 7, despite the release of newer operating systems of this family, still remains one of the most popular and in demand among users around the world, due to its versatility. But, as it turns out, it is not always possible to use some applications installed by the user. Most often, such situations appear at the installation stage. But why aren’t programs installed on Windows 7 that, in theory, should work on it without any problems? There are many reasons for this, which will be discussed further. But only the most basic and most common problems are offered for consideration, since it is simply impossible to cover them all, especially if we take into account each specific case of failures and errors.
Causes of iTunes installation error on PC
So, you decided to install iTunes on your computer, but you are faced with the fact that the program refuses to install. In this article we will analyze the main reasons that may affect the occurrence of such a problem.
Reason 1: System failure
From time to time, various failures and conflicts may occur in Windows OS, which can provoke the appearance of various problems. Just restart your computer and then try to install iTunes on your computer again.
Reason 2: Insufficient account permissions
To install all components included in iTunes, the system requires administrative rights. Because of this, you need to make sure that you are using an account with administrator rights. If you are using a different type of account, you will need to sign in with a different account that already has administrator rights.
Try also right-clicking on the iTunes installer and in the context menu that appears, go to “Run as administrator.”
Reason 3: The installer is blocked by antivirus software
Some antivirus programs, trying to ensure maximum user safety, block the launch of processes that are in fact not malicious at all. Try pausing your antivirus program for a while, and then try installing iTunes on your computer again.
Reason 4: Remaining files from the previous version
If you previously had iTunes installed on your computer, but after uninstalling it, a new installation attempt fails, it is likely that there is garbage left in the system from the previous version, which prevents you from installing the program on your computer again.
In this case, we recommend that you use the Revo Uninstaller software product, which will allow you to remove not only the remaining software, but also folders on your computer and registry entries that may cause installation problems.
Using Revo Uninstaller, you will need to find and remove the following iTunes-related programs:
- iTunes;
- QuickTime;
- Bonjour;
- Apple Software Update;
- Apple Mobile Device Support;
- Apple Application Support.
After you've finished cleaning your computer of unnecessary programs, restart the system and resume trying to install iTunes on your computer again.
Reason 5: Problem with Windows Installer
There are two common errors associated with Windows Installer. Let's look at both of them in order.
Windows Installer package error
Users who are trying to reinstall a program by uninstalling it, or simply running the installer on a system that already has iTunes and receiving an error message, can easily fix it by running a repair. Follow this instruction:
- Go to Control Panel and select Programs and Features.
Find "Apple Software Update", right-click on it and select "Repair". Once the iTunes installer window opens, follow all of its prompts until the recovery procedure is complete. In the same way, you can restore any other Apple applications with which you encounter the error in question.
Viral impact
Finally, the real scourge of all Windows systems is virus applets. They penetrate the system in various ways, affecting its important components, but most often such threats can be found on all kinds of torrent trackers. Therefore, after downloading files from such Internet resources, they must immediately be checked with some kind of portable scanner. But even here it should be clearly understood that not all modern viruses can be detected by anti-virus scanners. Some of them (for example, advertising applets called browser hijackers) can disguise themselves as official affiliate programs and penetrate the system completely legally.
Lack of rights
You must log in with an account with administrator rights. If, as a result of a system failure, your account no longer has administrative access rights, you need to restore them. This can be done using the ntpasswd utility. Next, log in as the “Administrator” user and perform the following actions:
- go to the user account settings through the “control panel”;
- select “manage another account”;
- select the required user account;
- Click on “change account type”;
- set administrator access and click the “change account type” button:
Installer problem
The inability to install the iTunes program on Windows 7, and many other applications, may be the result of a disabled or malfunctioning Windows Installer. If, when starting the installation, the system application displays an error window, you need to enable the service or reinstall the installer component.
To run the installer, follow these steps:
- Through the “Start” menu, launch “Run” and enter the command “services.msc”;
- In the window that appears, find “Windows Installer”:
- Double-click to open the service management interface and select “manually” from the drop-down menu:
If you have a version of Windows Installer lower than 5.0, you can update the component by downloading it from the Microsoft website. If the installer version 5.0 fails, it is more difficult to fix the error. There are 2 options: either reinstall the system, or use the method described in the article https://habrahabr.ru/sandbox/33155/, this method is more suitable for highly qualified users, programmers or system administrators. Nevertheless, the method is guaranteed to solve the problem.
Using Compatibility Mode
But some outdated applications (or even their installation), which work without problems in earlier versions of Windows, are sometimes advisable to run using the so-called compatibility mode.
In Windows 7, in this case, the installer or installed application will recognize the OS not as the seventh version, but as an earlier modification. Please note that upgrading the system version is not provided, that is, in the seventh modification there is no compatibility with Windows 8, 8.1 or 10 at all (although theoretically all four systems can ensure the correct operation of the same program). You can select the desired mode through the properties of the file being launched, using the properties item and the corresponding tab on which the required version of the operating system is selected from the list.
Service error
The error shown in the figure below ( An error occurred during the installation of assembly, Microsoft.VC80.CRT, version=»8.0.50727.4053″, type=»win32″, publicKeyToken=»1fc8b3b9a1e18e3b», processorArchitecture=»x86″. Please refertoHelpandSupportformoreinformation. HRESULT: 0x800736B3 .) indicates that the Windows Component Installer or Trusted Installer has failed, or that the service is disabled for some reason.
First of all, we check the status of the service; to do this, go to the service management console and set the launch manually, as shown in step 2, and click “run”; if an error occurs during startup, then you need to reinstall the component. You can also fix the error by running the “troubleshooter.” To do this, you need to download Microsoft FixIT from the Microsoft website at https://go.microsoft.com/?link >
Removing a digital signature
If the digital signature of a third-party program installer does not pass security checks, you can remove it. Special utilities are used for this. The most famous is FileUnsigner.
- Unpack the downloaded archive with the program and launch FileUnsigner. No installation required, it is a portable application.
- Grab the executable file of the program you are unable to install and drag it into the FileUnsigner interface.
We simply take the installer EXE file and add it to the digital signature removal utility
After removing the digital signature, Windows 10 should stop swearing at the installer. This will allow you to install the program. The main thing is that the system’s fears are not confirmed, and that you do not install malware by mistake. Remember that any disabling of pre-installed security features leads to a decrease in the security level of Windows 10. If to perform some task you are forced to deactivate User Account Control or enable the hidden “Administrator” account, then be sure to return it to its original state.
Garbage from the previous version
It happens that when installing iTunes, the system gives an error:
In this case, you should use the Windows Installer Clean Up utility. After completing the utility, through “Control Panel -\u003e Install programs” we remove applications:
- AppleApplicationSupport
- AppleMobileDeviceSupport
- AppleSoftwareUpdate
- Bonjour
- QuickTime
In safe mode, we delete all folders called iTunes in the user profile and the C: Windows folder. And repeat the installation.
If it doesn’t help, you can try using an archiver to extract the AppleSoftwareUpdate.msi file from the iTunes installation package and specify the path to it. After which the installation or removal will continue.
If the system does not boot
In some cases, BSOD appears when Windows boots. This makes diagnosis much more difficult. In the case when the system cannot be booted, and the blue screen appears for a moment or does not appear at all, you need to disable automatic reboot when turned on.
Another option is to use a bootable Windows LiveCD, which contains a large number of utilities to help diagnose the problem.
1. The first thing to do is remove the “overclocking”, if there is one. That is, all BIOS settings need to be set to defaults (by default) and all programs that speed up the system bus or speed up the video system should be removed from startup.
2. If your computer restarts, then you need to disable automatic reboot, to do this you need to click “start settings control panel system”, in the window that opens click “advanced” open the parameters of the “startup and recovery” item there you need to uncheck “perform automatic restart " After this, instead of rebooting, a BSOD (Blue Screen Of Death, popularly known as the “blue screen of death”) should appear.
If your computer freezes or the blue window does not appear after disabling automatic reboot, look at the standard Windows logs (Control Panel=>Administration=>Event Viewer) sections System and Application. Check events with type "Error". Using the ID and Source of these events, you can try to search for a solution on EventID.Net or in the Microsoft Knowledge Base. Instead of the built-in Event Viewer utility, it is more convenient to use Event Log Explorer™ or other similar utilities with advanced capabilities.
3. If Windows reboots without starting, then during boot you need to press F8, the boot menu should appear, you need to select the line “Disable automatic reboot when the system fails”, after which a blue screen should appear.
4. If a blue screen appears, quickly get rid of everything that can be read. After that, go to the site https://www.oszone.net/display.php? > If disabling automatic reboot does not save you from rebooting your computer or the description of the error on the “blue screen” does not give you anything, then perhaps the following points will help you.
Incorrect launch of program services
A very unpleasant error occurs at the final phase - failure to start iTunes services. Without them, iTunes can only be used as a player...
Good afternoon friends. Why is iTunes not installed on Windows 7 (32 - 64) bit? In this article, we will look at this problem and other errors that relate to installing iTunes on a PC running Windows 7. We will also look at the cause and find out a method to resolve it.

User has insufficient rights
Log in to your account as an administrator. But, if due to an OS error your account no longer has such rights, you need to restore them. This is done using the ntpasswd . Then, log in as administrator and do the following:
- Let’s go to the account settings using the “Control Panel”;
- You need to select the “Manage another account” command;
- Now it is advisable for us to select the desired account;
- Click on “Change account type”;
- Place a checkbox above the “Administrator” command and click on the “Change account type” link.
Next, log in using your account and install the software.
Why is blocking needed?
In most cases, this behavior of Windows is completely justified and you should not take any action to bypass the blocking. System protection in the latest versions is implemented at the proper level and the risk of running potentially dangerous or malicious programs is minimized. To protect against the launch of malicious code, driver signatures, various digital certificates, account control and some other functions are used.
The first thing you should do if you are prohibited from installing a downloaded application is not to rush and remember where the installation file that was not passed by the Windows security system appeared on your computer. Perhaps it seemed that the much-needed driver or other installer was downloaded from a site with a dubious reputation and having nothing to do with the manufacturer of the necessary software. In this case, it is better to visit the official website in search of suitable software and download the necessary program, and if it is not available, it may be worth refusing to install suspicious software.
Unfortunately, sometimes situations arise in which seemingly programs downloaded from official sources are blocked by the system for no significant reason. This situation is possible, for example, when installing a printer driver that the system considers obsolete due to the end of the technical support period, although the printer itself is working properly and has no breakdowns or failures. In this situation, most blocking cases occur when the installer certificate is expired or the application digital signature is incorrect.
It is also possible to remove the digital signature from the installation file (for example, using a third-party utility FileUnsigner ).
Because The application launch is blocked by the UAC system; you can temporarily disable it.
You can disable UAC through group policies. UAC policies are located in the GPO section Windows Settings->Secutiry Settings -> Security Options . UAC policy names begin with User Account Control .
Removing junk from the previous version of iTunes
Often, when you install iTunes, the OS shows an error:
Or like this:
This means that we need to use the Windows Installer Clean Up utility. When the utility completes its work, we will need to remove the software shown in the screenshot:
By going into “Safe Mode”, we uninstall each folder that contains the name iTunes from the user account, and the C: Windows folders. Then you need to repeat the installation.
To enter this mode, at the beginning of the system startup, press F8 several times. In the black window that opens, select “Safe Mode”. In this mode, many PC functions are disabled. But, the ability to delete elements works.
If this does not help, then you should use the archiver from the installation package to copy the AppleSoftwareUpdate.msi and specify its address. Then, it will continue installation and uninstallation.

Service failures
The failure that we see in the screenshot indicates an error located in the “Windows Component Installer” or Trusted Installer. Also, it may show that this service is disconnected for various reasons.
So we need to check the status of the service. To do this, let’s go into “Service Management” and manually start the desired service, as we did in step one. Next, you need to click “Run” and, if an error occurs, you need to reinstall the element.
Unsuccessful launch of software services
When you are already completing the repair phase, an error may appear when starting the iTunes service. Without these services, iTunes can only be used as a player.
It is quite possible that this failure occurred due to the fact that you did not perform the installation from Windows 7 administrator mode. At the same time, there are several methods to solve the problem.
- Click “Skip”, restart Windows and then start the services yourself using the msc ;
- We interrupt the installation and carry out it again;
- Disable UAS using the “Control Panel” and click on the “Retry” button.
Conclusion : - The problem “Itunes will not install on Windows 7” can be solved in various ways. We have now reviewed the main ones. I advise you to review the article again and choose the best option for you. Good luck!
Avast for Windows 10
Both on the official Microsoft forum and on other forums you can find discussions regarding the installation of such a popular antivirus as Avast on Windows 10. Many users complain that all attempts to install the defender end in failure. The system blocks the installation of the program. At the same time, by disabling the firewall, Windows 10 allows you to install the software, but after rebooting the system it blocks Avast again and turns on its defender. In addition, a number of problems arise during program uninstallation. Therefore, we will consider all the options for correct installation and uninstallation of this antivirus.
