Ok, I held down shift before clicking the Music Bee icon and it did bring up choose which library, but there was no library to choose from. I must have deleted that when I reinstalled windows, maybe.
Long ago, I moved everything off my system drive as windows likes to eat itself alive and I find myself reinstalling windows every 2 or so years, so it became difficult keeping my large documents files backed up, etc., so I run 8 drives on my system with one drive dedicated to my music collection. I was hoping Music Bee would store it's info on that drive, yet it does not, unless I install it there as the portable option, which I don't like because then that folder bumps into my dedicated folders (classical music collection, very large very complex). So, I thought I had backed up the library, but apparently not.
So, is the portable version the only version I can use that will essentially allow me to leave my collection alone on a drive that never gets touched by windows?
