Damaged Student Edition files prevent Upgrade

I have SW Student edition.  I have just purchased the upgrade (\\\$49) thru Cleverbridge.  I downloaded the setup.exX file but after it gets to the "Summary" and I press "Modify now", I get the Msg: The Installed Toolbox folder cannot be found: C:\\SOLIDWORKS Data (5)

Of course, I tried creating the missing folder.  

What do I do?  

I'll never get the present install repaired so that I can upgrade it.  

Can I uninstall SW and run the same setup program and get a fresh number?
