Hi Francesco
I have the Vista drivers on a disc. I have installed them and THE PRODIKEYS IS NOW WORKING FULLY!!!
Wonderful!
As you say the problem is with 64bit, not Windows 7. I had my new PC changed to 32bit recently, and by doing that, and installing the Vista drivers, it is working properly. Many thanks for suggesting the Vista drivers. Hope this is of help to anyone else trying to get the Prodikeys to work.
