Windows 7: Registry Entries Keeping Me From Installing Program

I have a fresh install of Windows 7 Pro 32 bit and all my software is installed and working well except for one. Following a problem with the initial install attempt, I'm trying to re-install LotusSuite 9.8.2 but the previous attempt seems to have resulted in some "Lotus" registry entries that now direct things to a non-existent "F" drive. When I try to re-install from the CD, it doesn't allow me the option of choosing the destination location. Instead, it automatically tries to install in this non-existent drive. I've opened RegEdit and searched and found many references to Lotus and to F:\Lotus.

How can I edit the registry to get rid of the F:\Lotus entries or change them to C:\ ? Or just get rid of all references to Lotus?

BTW, this software works perfectly on my Win 7 laptop.

When finding the entries for F:\Lotus you can try changing those to C and then try running the installer again to see how it goes. Otherwise with the program uninstalled you would simply delete those entries and try another fresh install to see if that will run into the same non existant drive problem.
