I just backed all the files up to another external hard drive (where I keep all my installables, so I never have to look for CDs).

However, what I found when I tried to install from that backup copy was, since I put it into a subfolder, the installer program wouldn't work anymore (from the backup hard drive). So I found I can use the old DOS "subst" command to essentially make the computer think the installer was in the root directory (for example, subst o: "l:\apps\install\pgmusic\biab2010ultra"). That worked great for XP and Vista, but would not work on Win7. I ended up using the original USB hard drive to install to Win7 (I install everything locally and leave the orginal USB hard drive as another backup copy of the original files). I now have two copies as a backup, plus the installed version on my computer.

Disk space is relatively cheap. It's a good insurance policy to back everything up. You can find some good deals at CostCo and Newegg.
