I downloaded and installed HOTISO's 64 bit enterprise... can't get it to activate!!! I've tried Orbit's 1.4 loader, Hazar's manual method, and a couple of others... I either get messages that the DNS server is invalid, the key is invalid, or exceeded it's limit... I also have a HFS+ partition on the drive, if that matters.... Please, how do you activate 64 Enterprise win 7?
