I have two windows 7 desktops with Virtual System Pro 2011. One of them has a hard drive that is starting to fail. I am going to replace the hard drive and re-install Windows 7 again from the recovery discs (the bad sectors have corrupted some system files). Two questions: 1. How do I determine what one of my two licenses is on the bad hard drive machine (They were bought and installed at the same time.) 2. How do I transfer that license to the new install on the new hard drive? Thanks for any assistance.
