I've upgraded from TI 8 to TI 11 Home on my XP machine. I did this without uninstalling the old version first, which was probably a bad idea. Although TI 11 works fine as far as I can tell, device manager now shows two instances of "Acronis TrueImage backup archive explorer" and I'm not sure if it's supposed to do that. The "driver" tab shows one device dated 13.03.2002 and one dated 15.11.2005. My question is: can/should I delete the older device, or is it needed for compatibility with TI 8 image files or something like that?
