Hello! I am having a problem installing ".NET Framework 3.5 (includes .NET 2.0 and 3.0)". The computer is Windows 11. Error code 0x800F0922. I tried to solve the problem as written on the Internet, nothing helps.

What steps have you followed to solve the problem?
Are you using any application which required older version of Microsoft .NET?
I used the wushowhide program. I tried to install via the command line and I got the error "The process cannot access the file, because this file is occupied by another process." And also methods from sources: https://gamesqa.ru/kompyutery/kak-ispravit-oshibku-0x800f0922-vo-vremya-ustanovki-net-framework-3-5-5348/, https://pc103help.blogspot.com/2021/03/fix-windows-10-update-error-code-0x800f0922.html. And also using various YouTube videos. I need it for programming, but after updating my pc, I cannot reinstall .NET Framework 3.5.

Hi @Даниил ,
Take a look at the document about the installation of the .NET Framework 3.5.
Troubleshoot the installation of the .NET Framework 3.5
Hope it could be helpful.
In case it happens after installing an update, try uninstall it and restart your PC and see if the problem persist?
Try visit Visual Studio Feedback website and click on Report a problem and then select .NET and file a bug report, take a look at:

Hello 03275801,
Thank you for your question.
This may be a specific issue with wushowhide, I recommend initially contacting their support team and reporting this issue.
The next step would be to look for the windows 11 forum, because this may have already been reported by other users.
To do this, access the link below and from the top menu select "Ask a question" and describe the entire problem, including images:
