I don't have direct knowledge of this issue, but found these details about my local installation.
I see Intuit data at:
C:\Users\USERNAME\AppData\Roaming
(I see a license file at the above location)
C:\Users\USERNAME\AppData\Local
I see regedit registry data at:
HKEY_LOCAL_MACHINE/SOFTWARE
HKEY_USERS/SOFTWARE
Uninstall, rename away the above data (don't delete, just in case you end up needing it later), and reinstall.
