Windows update error 0x80070643 for Windows 11 Pro

[Sammy815]

I'm having issues in using windows update as I'm getting error for 2021-10 .NET 5.0.11 Security Update for Windows 11 for x64 Client (KB5007051) and 2021-10 .NET Core 3.1.20 Update for Windows 11 for x64 Client (KB5007050). I've tried to reset the windows update, I've run DISM and SFC and nothing seems to fix it. 

Can someone help me please?

Same problem windows 11

Installation error 0x80070643  2021-10 .NET Core 3.1.20 Update for Windows 11 for x64 Client (KB5007050)
Installation error 0x80070643 2021-10 .NET 5.0.11 Security Update for Windows 11 for x64 Client (KB5007051)

I Wonder if this causes the problem i see installed this update 09-11-2021-11 .NET Core 3.1.21 Update for x64 Client (KB5007885)
Its higher than the other update that cause the problem for install.?

ciao anch'io avevo questi due errori ma il primo
(Installation error 0x80070643 2021-10 .NET Core 3.1.20 Update for Windows 11 for x64 Client (KB5007050)) l'ho risolto installando il kb direttamente dal sito microsoft: https://www.catalog.update.microsoft.com/Home.aspx

Provato anche con il secondo ma l'errore persiste

[#11]

hello I too had these two errors but the first
(Installation error 0x80070643 2021-10 .NET Core 3.1.20 Update for Windows 11 for x64 Client (KB5007050)) I solved it by installing the kb directly from the microsoft site: https://www.catalog.update.microsoft.com/ Home.aspx

Also tried with the second but the error persists

@Al3xI98O 

I think the issue for me is that I don't have the listed versions of the software installed. If I check Apps & Features, I've got Microsoft ASP.Net Core 3.1.21 and Microsoft ASP.NET Code 5.0.12 installed. Whereas the updates refer to 3.1.20 and 5.0.11 respectively.

[#13]

@Sammy815 I am facing the same issue with upgrading of  2021-10 .NET 5.0.11 Security Update for Windows 11 for x64 Client (KB5007051) & 2021-10 .NET Core 3.1.20 Update for Windows 11 for x64 Client (KB5007050). My system has also become slow after upgrading it to Windows 11 from windows 10. Now I cant downgrade it to windows 10.

@Aditya2245 I checked the windows update today and the [corrupt] updates are replaced with new ones and it has installed all updates successfully. :)

Just happened to me installing 2021-12 .NET 6.0.1 Security Update for x64 Client (KB5009191)
Install error - 0x80070643

Please let me know of any fix. Thanks!

I downloaded .NET 6.0.1 SDK installer from this link (https://github.com/dotnet/core/blob/main/release-notes/6.0/6.0.1/6.0.1.md) and installed it. It's fixed.

[#18]

Thanks. I got the same issue and your solution worked.
