We have a client who is running MS Office 4.2 on Windows NT 4.0 with Service Pack 4 installed.

Office runs fine until he installs our Visual FoxPro application [built using VFP 6 SP3].

Once he has installed our application, any attempt to run any MS Office application gives him a messagebox. The title of the messagebox is "Can't Run 16-Bit Windows Program" and the actual message is "This application is not supported by Microsoft Windows NT".

Has anyone seen this problem before. I'll be doing further testing when I get into the office on Monday morning.

Best.

Matt.
