Well, since it's looking for 32 bit programs, thought I'd go the other route and reinstalling the 32 bit version. Afterwards, both the 32 & 64 bit versions work, and I can see where the bookd were stored. Both the catalog and all the books seem fine. BTW, where is the catalog stored so I may back it up?
So, at this point, if I uninstall both versions and reinstall the 64 bit version, is it likely that the catalog and books will remain as they are and accessable, and that I will not need to do anything else after the install?
