I'm having a problem running win32 guided tour application on 64 bit windows OS. The application is running smooothly on a 32 windows OS server 2003 but migrating it to 64 bit error always occurs. It says that it is not valid given the right keygen. I;ve made research and I've learn it is done with 64 bit, wondering why I'm encountering such problem. Is there any way to solve this error?
