I have tried unistalling framework 4 and reinstalling using the standalone installer. I have also used the framework clean up tool with no help. I have tried to repair the installed framework 4 with no success. I have tried all of this with my antivirus turned off and I have tried to use Microsoft fixit along with running Ccleaner registry fix.
This 643 Error is driving me crazy any help would be great.

Let me know if it helps.
Thanks for the Input!
However, I am still having this issue after trying to give myself the permission, which I already had.
I think it's probably time to do a repair of Windows. The only other option would be to talk to your computer manufacturer or Microsoft technical support to see if they know a way to fix the error.
