Ok, when I started using Calibre I was using the E:/ drive on my computer. However, something happened to the drive and when I had it fixed, I transferred everything to another drive - F:/
Now my problem, while Calibre itself runs great off the F:/ drive, it WILL NOT upgrade. Every time I've tried it starts the installation wizard and then comes back with an error that says cannot install to E:/...how do I get the install wizard to install the upgrade on F:/ and not E:/???????
