I saw the rules and I dont think i am trying a hack.. I have a vista HP lap top I bought a year ago...I bought an HP tower 4 months ago and it qualifies for a free windows 7 up grade kit..june 2009 and newer I got the kit thinking I could install it on the older but in HP warranted laptop..The kit has 2 disk and it could tell it was being installed on a non qualifying laptop and would not let it continue...I only want to install on one PC, I figure hp could see if I put it on another PC later. Is there a work around...something to fool the thing and let it continue. If I cant use it on my laptop I will trash it. This kit seems like it does not have the full window 7 program, but an add on to the vista to alter it...the instructions made it clear it would not work unless updated vista was already installed. If you had bootleg 7 or XP on the laptop they wanted you to uninstall and put back the original vista.
