Windows 10: .NET Framework 3.5

I am trying to get .NET Framework 3.5 to install on my computer in order to use an application called Rustangelo, however I have not been able to get it to install whatsoever, I have followed every troubleshooting guide I have managed to find on google and I have even tried to manually install it along with another windows update that I am missing and even the manual offline download failed. I am at a loss here and it's starting to piss me off that nothing whatsoever is working. Any help is much appreciated.

Error code I am getting is Error 0x800f0805

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,
