You may need to reinstall .NET Framework and all the updates.
When you install .NET Framework you may need to disable your antivirus software
first.
Try starting over by going to Add/Remove Programs with "show updates"
checked. Remove all .NET Framework entries including updates.

Then go to MS site and download & reinstall theLtest .NET Framework and updates through manual
download, restarting as necessary.
Only after successfully reinstalling and restarting should you re-enable your antivirus software.
