- Renamed C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys folder to MachineKeys.old
- Recreate C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys folder
- Moved C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys.old to C:\Temp\
- Re-run the installer

Hey nobus:  Thank you for the quick answer.  That did not work.  Should I have rebooted before re-running the installer?

Download the tool from this link and run it,

Hey guys.  Thank you greatly for all of these solutions.  None of them worked for me.  I am thinking I may have to do a repair installation recommended by nobus above.

Yes Repair install is a good option as suggested by Nobus. sometimes it needs a fresh Windows install to be fixed.

Please also uninstall your Antivirus and test again.

Did you try System Restore ?
