Windows 10: Microsoft .NET framework wasn't installed, what causes this and how do I fix it?

I have had problems with installing Windows updateserror: 0x80070643, and it was recommended that I install the most recent .NET framework. I tried to install but received an error message. It reads ".NET framework 4.8.1 has not been installed because: The requested operation failed. A system reboot is required to roll back changes made." How exactly do i fix the issue, and what is the cause? Also, how do I do a system reboot safely?

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

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.
