I put together a comp. with parts of my brothers old comp. For my brother to have a new 1 ,but he wanted programs like office "which is on his old Hard drive" and my widows vista business that I have doesn't have office . So I thought maybe I could put his old hard drive as a slave drive and he would have all his old programs ,but it say's they won't run on that OS. Is there any way around this or am I better off getting office somewhere and fresh installing it ?His old Comp. was a Dell.
