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!!

 

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

Phil,

This might all be pretty confusing now.

I suggest

1 Turn on updates for other MS products - my post #22
2 Run WU to see if it now shows that KB4586876 .Net update as being required

3.1 If WU lists it then install it.
4.1 If it installs and there are no remaining problems, stick the kettle on.

3.2 If WU still does not list it then use that .Net fixer tutorial I gave you a link to - my post #18
4.2 If the problem defies the fixer tool then study the Ghot guidance in that other thread I gave you a link to [ - my post #18] and consider Ghot's suggestion of re-installing the runtime [his post #21].
5.2 If it refuses to install, try reinstalling v3.5 - Install .Net Framework 3.5 - TenForumsTutorials The update is for both 3.5 & 4.8 but I suppose there's a chance that reinstalling 3.5 would give something a kick up the pants enough to get it all working.
6.2 If it still won't play, consider unloading then reloading both .Net entries in CP, P&F, Turn Windows features on & off. We used to do that for WMP in Windows 7 so it is a pretty well-established method but I have not seen anybody apply it to .Net entries before so you might want to discuss it further before doing anything about it.

Best of luck,
Denis

12:29 - I have now finished fiddling with this post.

 

Install .NET Framework 3.5 on Demand

It would be an update, but unrelated or required for installing .NET Framework 3.5. *Smile
