Yes, this means that even if you have a licence that it's still available, the problem will be with the software. The compatibility of the software is with older versions of Windows and 64bit isn't supported at all. This means that you won't be able to use it in a 64bit environment. The fact that it's running in Windows 7 it's just pure luck. If you switch to 64bit, a message will say that the program wasn't developed for 64bit operating mode.
