If I try to add books to the new, empty library (actually in a new location), Calibre seems to add them and they then show up in the library as they are supposed to, however when you try to open one, you get a message to the effect that the book has no content.

It also tells me that many of the new books I'm adding to the new library that were in my old library are duplicates, but not all of them....something is corrupt.

I have given up on the software and am reading reviews on other software. If un-installing the software leaves registry entries that cause problems with a new install, I can't see using that software again.

Can anyone suggest a system to look at that they have experience with?
The problem seems to be that your library and preferences are surviving the uninstall which is by design to allow you to uninstall calibre and reinstall without losing data. This is nothing to do with the registry. My personal suspicion is due to it's multi-OS support, calibre does surprisingly little in the registry

Unless you have manually changed calibre's install locations, for a clean uninstall, you have to uninstall calibre and then manually remove the calibre library directory/directories (you can have more than one though a search for metadata.db should locate them) from your Documents directory, the calibre-cache directory from your AppData\Local directory and the calibre directory from your AppData\Roaming directory.

Then you should be able to install a new instance of calibre with no remnants of the old install.
