Go to and check your
Adobe registration through support. If you downloaded the program, I sure hope you registered it! The program should have info on your product key under "help." You might have to look around a bit. It may be under help, then "about."
Even if the info is there, before you upgrade, I would still go to Adobe support and make sure that you can register and use the info provided.
I see a lot of people that can't get the activation accomplished even when they have the info.
Finally, I hope you know what you are getting into with a "clean" install over XP. It is a bit complicated. If you have never done it, take the time to
check this out at Microsoft.Good luck! Thanks for stopping by Fixya.
