Windows 10: .NET Framework 3.5 error

When I try to install .NET Framework 3.5, I get the error code 0x00F0900. I have tried many things, but nothing has worked

:)

 

Unable to download any framework for .net - (error code 0x80070002)

OK, the Windows 10 Feature installation method should have been straightforward, but since that errored out as well, something else seems to be going on with your Windows, so wait for somebody with more experience to suggest a way out.

In the mean time, if you haven't already, you could give muchomurka's suggestion a go as well with the elevated prompt and an install media to see if it works. The following link shows the detailed steps involved.

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.
