(1.11 MB)

Supported operating systems: Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7. The program can work as a step-by-step wizard, as well as in automatic mode.

What is Microsoft .Net Framework

One of the main components of the Windows operating system is the Microsoft .Net Framework. With its help, you can run programs and utilities that are written using the Common Intermediate Language (CIL) environment. The .Net platform translates program code using a compiler into a language that the operating system can process and execute.

Microsoft .Net Framework

The latest versions of the platform are currently installed through Center Update Windows. When you uninstall a component with a new service pack, the software will be re-downloaded to your personal computer.

Important! This utility must be installed on the device. If the platform is missing, applications will not be able to work correctly.

.NET Recovery

Method 1: Windows Updates

All files associated with the library in question are included in Windows along with the latest updates. Of course, it may seem that removing related updates will get rid of elements of the .NET Framework, but this is not the case, because Microsoft uses unusual algorithms for installing packages. Instead, you can try to disable existing library elements and try to update them the next time you install updates, which happens like this:

1. First, you must make sure that the next Windows 10 update is ready to install. After that, open Start and go to Settings.

In the menu that appears, select the “Applications” category.

Scroll down to the very bottom of the list, where you click on “Programs and Features.”

Through the left pane, navigate to “Turn Windows features on or off.”

The very first lines in the “Windows Components” window are responsible for the functionality of the .NET Framework. Uncheck them to disable them.

Wait for confirmation of this operation. This will take literally a minute, and then you can close the window with the components.

Now, through the same “Settings” menu, go to “Update and Security”.

Install the updates found and restart your computer.

Now we can only hope that all the missing files were downloaded and installed along with the latest update, which allowed us to fix problems with the functioning of the .NET Framework. Don’t forget to enable these libraries through the “Windows Components” menu immediately after logging into the OS. However, in some cases there are additional problems associated with installing updates. Then the user will have to solve them additionally. We suggest reading related guides on this topic in our other articles linked below.

Method 2: Install Visual Studio

Visual Studio is a proprietary software from Microsoft that is used to develop applications in various programming languages. First of all, the manufacturer aims to ensure correct interaction of this development environment with Windows, because many utilities and software are written specifically for this platform. This will allow the average user to use Visual Studio for their own purposes by checking the missing .NET Framework files.

1. From the official Visual Studio website, select the Products pop-up list.

In the menu that appears, you are interested in the inscription “Applications for Windows”.

Scroll down the tab and find the “Visual Studio Community” version there. It is distributed free of charge and is completely suitable for our task today. Click on the “Free download” button to start downloading.

After that, run the resulting installer.

Wait for all components to download for installation. During this process, do not interrupt your Internet connection.

When the installation window appears, move to the Individual Components tab and check all versions of the .NET Framework.

We have just described one basic action that must be performed as part of today's instructions. As for the operation of downloading Visual Studio and its installation into the operating system, a separate article on our website is devoted to this topic, so we recommend that you read it to complete the installation process and check the functionality of the .NET Framework files.

This was all the information about reinstalling the .NET Framework in Windows 10. As you can see, this operation in the usual sense cannot be carried out, and you can only try to fix missing or damaged files. If this does not help, try using the troubleshooter, which you can read about below.

If this manipulation does not bring the desired result, you should pay attention to the assembly of the operating system itself. Most likely, you downloaded a broken repack from pirated sources, and the only way to get rid of the problem with the .NET Framework is by reinstalling Windows using a different assembly

Why is removal necessary?

It is necessary to remove a system component in a situation where errors occur when launching applications. If a user has the latest version of a program installed, but the application does not see it and requires a re-installation, this means that critical files and support services have been damaged.

System requirements for optimal performance of the .Net Framework

The hardware requirements for normal operation of
the .Net Framework are quite low, so the component will work even on the weakest computer. The rest of the information in this chapter is primarily intended for first-time users. For the more advanced, skip ahead to the chapter where you will learn about the latest version of the .Net Framework available for installation on your OS. Your computer is required to:

• Processor with a frequency of 1 GHz or higher;
• The amount of RAM is at least 512 MB ;
• The minimum amount of hard disk space is 4.5 GB .

The .Net Framework has quite a few versions that have been released since the days of Windows XP, but there have been no major changes in the architecture of the component. Remember that the version of the .Net Framework on which this or that program was developed will require the corresponding ( 2, 3, 4 ) version on your computer.
Therefore, for best compatibility with the maximum number of applications, all possible variations of this component should be installed. But this does not mean that the latest libraries will be fully supported by older operating systems. Sometimes, in order to install the appropriate version of the .Net Framework, you need to upgrade to a new version of Windows. We strongly recommend that users install Windows 10. ↑ Return

Error when installing .Net Framework 3.5: 0x800F0906, 0x800F081F, 0x800F0907 on Windows 8 or 8.1

This issue occurs when you try to install
.Net Framework 3.5 . Before performing the steps below, it is recommended that you read the chapter: “Error installing .Net Framework update 0x80070643 on Windows 7.” Errors 0x800F0906, 0x800F081F, 0x800F0907
in most cases appear when installing the .NET Framework 3.5, when the operating system has security updates
KB2966826 and KB2966828 .
This is most likely due to the fact that some Windows updates may not be tested to work or interact with the .NET Framework 3.5 installer.

MS developers assumed that users would use new, more current versions of the Framework, and the .NET Framework 3.5 installer itself was created long before these updates, and does not take into account the changes in policies and security mechanisms that they bring.

To use .Net Framework 3.5 (and below) on new OSes, you must:

1. Temporarily disable Windows Update ;
2. Remove KB2966826 and KB2966828 through the standard Add or Remove Programs tool;

This may be a rather non-obvious choice, for example drive A:, or another drive not intended for these tasks. To get around this problem, just run the installation using the command line (see Figure 5):

1. Launch the command line: open the “Start” → write in the search bar: cmd → launch the corresponding program by left-clicking the mouse;
2. Go to the installer package folder using the command “cd C:\my-install-dir”
3. Run the installation package with the key "/x":
