I was installing .NET 5 and it kept saying Setup Failed. The error is "0x80070659 - The installation is forbidden by system policy. Contact your system administrator". How can I solve that problem? Installing .NET 6 and .NET 7 works completely fine. The logs in the log file are as follow: [33C4:1F6C][2023-05-04T16:30:57]i001: Burn v3.14.0.5722, Windows v10.0 Build 22621: Service Pack 0, path: C:\WINDOWS\Temp\{529C0F0F-C732-4851-979B-CF363773375C}\.cr\dotnet-sdk-5.0.214-win-x64.exe [33C4:1F6C][2023-05-04T16:30:57]i000: Initializing string variable 'DOTNETHOME' to value '[DOTNETHOME_X64]' [33C

KB4025339 Fails Install 0x80070564

Thanks
I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
Did step 3 KB has downloaded but fails to install.

If Eagle's suggestion doesn't work I'll try EdTittel's suggestion

Tried bothe Eagle & Ed 's suggestions - do not work. Anyone else?

I have noticed that the latest update for my nvidia drivers has failed to update. Wondering about that!

Unable to download any framework for .net - (error code 0x80070002)

OK, the Windows 10 Feature installation method should have been straightforward, but since that errored out as well, something else seems to be going on with your Windows, so wait for somebody with more experience to suggest a way out.

In the mean time, if you haven't already, you could give muchomurka's suggestion a go as well with the elevated prompt and an install media to see if it works. The following link shows the detailed steps involved.
