Attempting to reinstall .NET Framework Fatal Error (0x80070643)

[discostick]

A couple of my programs/games would not launch giving me a similiar error. After some research I believed it was a problem with .NET, well now I can't reinstall it. I've tried numerous things that have been mentioned on this forum. I'm going to copy and paste the error log that Framework gives me. I appreciate any help!
