So I was able to secure a corporate cd-key from my office. The copy of Business Vista64 I had produced an error multiple times. So I asked a friend who had Business Vista64 to burn me a copy of his disc which he got from school. Everything went as planned, booted from the disc, program's running and then I had my corporate CD-Key and the program states there is an error and the install program must be restarted! Any idea why this is happening? I thought all version of Vista were on the install disc, its just the CD-Key that unlocks which version gets installed?
