I was able to resolve this error.
For anyone else that might have this issue. What I had to do was go into the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Classes|Installer\Products and rename the file that was associated with Classic Shell. I believe I had version 4.2.1 and the file name for me was 8FC921C7F9919624AAEE065B8D7D621E. This allowed me to install Classic Shell correctly again.
After it installed correctly I ran the installer again and clicked remove and then restarted my machine. This fixed the issue for me.
THANK YOU! THANK YOU! THANK YOU! I have been trying to fix this all day! Your method worked. I owe you big time!
