so recently i received a windows update and before i went to sleep i started the update and went to sleep, when i woke up the next day i tried launching an app and it gave me the following error:

This application requires one of the following versions of the .NET Framework: v4.0.30319 Do you want to install this .NET Framework version now?

I clicked yes then downloaded the 4.8.1 version of .net framework, but i then realized i downloaded it in a wrong way and it didn't function properly, i reinstalled it and restarted my pc and now there it is. its the control panel meaning its WORKING but still showing the same error.. bandicam 2023-07-27 13-23-02-590

Hi @hamada98765 yup

In fact, I think you should download .NET Framework: v4.0.30319.

The .NET Framework 4.8 may have removed some libraries and prevented the program from running.

For example, I installed . NET Framework 4.8 but I still can't run Project for the .NET Framework 4.5.

Test2

At the same time, I suggest you go to the official website to download.

Hi @hamada98765 yup

This is the version of The common language runtime (CLR).

You can enter the command "clrver" in the Visual Studio console to see the version number that has been installed.

Usually this is followed by .NET Framework download included.

You can try installing it in Visual Studio Installer.

These documents I think will be useful to you:

Clrver.exe (CLR Version Tool)

Hi @hamada98765 yup

My suggestion is to make changes in Visual Studio Installer.

At the same time, I want to emphasize that the v4.0.30319 you mentioned above is the version of the CLR. Usually install .NET Framework 4.8 will come with this version of the CLR. So I think you can use Visual Studio Installer to view and uninstall the version number on your device, using the method above to see your own CLR version number.
