Solve the .NET Framework installation error: The system does not support the operating system

When installing the .NET Framework, you may encounter errors related to the .NET Framework version, such as "This operating system does not support .NET Framework 4.7/4.8". This article will provide several solutions.

.NET Framework is a programming infrastructure for creating and running software on top of an operating system. Although Windows 10 supports .NET Framework, not all Windows 10 versions are compatible. Therefore, you may receive an error message when trying to install the .NET Framework as a standalone service.

Here are some possible solutions:

Method 1: Disable the previous .NET Framework version

Turning off an older version of .NET Framework might be an effective workaround.

Step 1: Press Win R to open the Run dialog box.

Step 2: Enter optional features and click OK to open Windows features.

Step 3: Uncheck the other version of the .NET Framework in the list and click OK .

Step 4: Confirm the operation and restart the computer.

Method 2: Change the registry key

CSDVersion is a Windows registry value that specifies the installed service package. If the service package is not installed, the default value data is 0. We will change it to 100 so that the operating system thinks the service pack is installed.

Step 1: Enter the Registry Editor in the search bar and press Enter .

Step 2: Navigate to the following path:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Windows

Step 3: In the right pane, double-click CSDVersion > Set its value data to 100 > Click OK to save the changes.

Step 4: Restart the computer.

Method 3: Update Windows

If the above method does not work, you need to update your Windows 10. Installing all available Windows updates will be the most effective solution due to errors caused by operating system incompatibility.

Step 1: Press Win R to open the Run dialog box.

Step 2: Enter winver and press Enter to check your Windows version.

Step 3: To check if your Windows version is compatible with the .NET Framework version, you can access the .NET Framework version and dependencies page.

Step 4: Press Win I to open Windows settings .

Step 5: Go to Updates and Security > Windows Updates > Check for updates .
