Windows 10: .NET Framework error spam while .NET Framework is clearly enabled

For some reason, all of my software started spamming me that NET Framework isn't installed. OK. I tried to install net framework from official microsoft. It does say Successful on Net Framework installers but the software still do not work. Error is from one of the software I use, SmartSystemMenu. Also Net Framework 4.8.1 never lists in appwiz.cpl for some reason.Trying to install the specific 4.0.30319 will tell me that Windows already has this but it may not be enabled. Other error comes from microsoft store UWP, wanting version 4.6.0. Net framework is enabled on optional features. I used

:)

 

Microsoft .Net Framework

Basically, to sum up what I can tell:
-The application(s) that crashed use .NET Framework 2.0 or 3.5.
-First error is it getting nothing when it expected something (not very telling).
-Second error occured in "System.Data.SQLite" which is not .NET Framework. I repeat, not .NET Framework.
-SQLite is is a GNU licenced, free to use library.
-Any .NET-compiled service or process could be causing the error. If you watch the Task Manager, you might be able to tell which process closes after you click on "Quit."

I suggest you search your computer for sqlite*.dll. Whatever programs it is found in close proximity to are most likely the culprits for the crashes.

 

Microsoft .NET Framework, Unhandled exception

Hi,

Welcome to Microsoft Community.

I suggest you to un-check and recheck .Net framework 3.5 and .Net framework 4.6 advance series from Windows features.

Try the following steps:

• Press Windows + R keys to open Run command.
• Type Appwiz.cpl and select "turn Windows feature on or off" from the left
• Uncheck .Net framework 3.5 and .Net framework 4.6 advance series.
• Restart the computer
• Repeat step 1 and 2 and check .Net framework 3.5 and .Net framework 4.6 advance series.
• Restart the computer.

Regards,

 

Microsoft .Net Framework

.NET Framework is part of the Windows Vista/7 shell. If you deleted registry entries pertaining to the .NET Framework, you'll probably have to reinstall Windows.


Again, those error messages aren't .NET, it's some poorly coded application coded for .NET that starts on system startup that is crashing. Seeing as FireFox is the only app to have sqlite, I suspect it, or a component thereof, is the guilty party.
