Windows 10: .Net Frame 4.8 update on MS Sever 2019 failure

Hi. I need assistance PLEASE. I've checked probably all the solutions provided by other articles and unfortunately cannot fix the 4.8 installation. I've used the .net repair tool, manually installed updates, restarted specific services etc and still at a stale mate. Below are the errors from the logs. I really appreciate anything which can assist me in fixing this. Installation Errors: Action: Performing Action on Exe at C:\05e8fd7ba477667f73da6967bb8d\x64-Windows10.0-KB4486153-x64.cab Exe C:\05e8fd7ba477667f73da6967bb8d\x64-Windows10.0-KB4486153-x64.cab failed with 0x80092004 - Cannot f

WU .net 5.0.8 & 5.0.10 repeated install failure

It looks like - The 5.0 SDKs(3) installed on10 Mar; 12 Oct; 5 Nov (this one came from VS 2019 Community). An ASP.net was also installed 12 Oct.

The only manual installs were in the past 2 days trying to get this pc to accept the Dot Net updates. I have researched this on the web for several days trying all the suggested fixes and there has been no success. I installed manually .Net Runtime hoping that would correct the problem, which it did not.

 

KB4586876 Cumulative Update .NET Framework 3.5, 4.8 Windows 10 Jan. 12 Win Update

Hi Denis:
Thank you for your detailed instructions!! This will probably take several days & I'll keep you updated.

I did steps 1 & 2. This installed more updates than I could count...something like 20-30. However, KB4586876 was not listed. Unfortunately, I had to undo several things (I now remember why I didn't update all MS products). I have Word, Excel, & Access from 2003, as well as Word & Access 2016. Updating MS products caused a "file validation" problem whenver I opened a .doc file. I fixed that (with a registry hack). However, it did something to Word 2016, where all my .doc & .docx files were opened by Word 2003 & Word 2016 wasn't an option under "Open with...". I ended up restoring everything from Macrium Reflect.

I will now start with step 3.2.

Thank you. After checking again, my settings are the same as yours. Also, As Denis pointed out, I had looked at the wrong key. I checked the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full & found it to be the same as yours.

Hi @Try3 & @Ghut:

I tried to install the runtime from Ghut post #22 (Denis: your Step 4.2) & it said that I already had the latest versions installed. I then tried to reinstall .Net Framework & went to the catalog:
PHP Code: 2021-01 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 2004 for x64 (KB4586876)
Last Modified: 1/8/2021
but I couldn't download it. Basically, nothing happened & I got this image:



I tried Step 5.2 in post #26, but I show both 3.5 & 4.8 installed.

I guess I'll try Step 6.2 now...turning off .NET Framework 3.5 &4.8 & turning them back on. Before I do, do I need to reboot in between. I don't want to screw this up.

Thanks again to both of you!!
