I'm an old dog trying to learn old tricks. Due to an unfortunate sequence of events I am back trying to support a customer who is running a DF3.1 app on a Win XP computer. What are the issues if we try to run this app run on a newer version of Windows?

This customer also has a VDF 16.2 app (in test) running on the same computer. Will a VDF 18.2 compilation run under Win XP?

All help and advice is greatly appreciated!! Thanks
