Hello!

Once again I have to ask for help, now with new error code.
Went that way for three days, had no luck in reinstalling. Other updates for those dates work fine, no corruption found by SFCFix:

Hi,

Can you try the following:

Go to Control Panel > Programs and Features > select Microsoft .NET Framework 4 Client Profile from the list and click on the Uninstall/Change button. The Microsoft .NET Framework 4 Client Profile Maintenance window will open and select the “Repair .NET Framework 4 Client Profile to its original state”. Click next and follow the on-screen instruction.

If you have also the .Net Compact Framework 3.5 right click also on this entry and select Repair

After the repairs try to install only the problematic update, if it fails collect the new CBS.log after the error.

I haven't found "Microsoft .NET Framework 4 Client Profile", only had "Microsoft .NET Framework 4", tried to fix that and got internal error of other kind. But after I get standalone installer of .Net version 4.8 instead of 4.7.2 I had earlier, it had worked well, and Microsoft Update passed as well after the change; so the case I solved, I guess. Still don't know what could have caused such strange behavior, but it's working now, so that's good. Thanks for the advice! :)
