Hello, I just got a new comp, w/ win7. I just took the HD from my old comp, and added it 2 the new system, hoping that i could run some programs from it on the new comp, (because i've lost install cd's etc..) Everythings fine except, I cant run any of the programs. Like, Old drive has Microsoft Digital Media Edition. I tried to open it & run the install, but the new comp says.. cant access registry. New unit is win 7, old one was xp, sp2. anything i can do to use my old programs? can i copy the drive onto the win 7 hd? thanks for your help..
