Unable to start Foxpro database in Windows 7

Our old file server has died (WINDOWS NT)  and been replaced by a WINDOWS 7 computer with simple peer to peer networking to other notebooks and PC's in the office which are all happily running a mixture of  VISTA and XP.

Our primary office database of business records ( Addresses, dates , who, etc) is a FOXPRO database we developed some 12-15 years ago.

Its solid fully self contained, robust, and will happily run straight off a USB memory stick in a VISTA, XP, 2000, 98,95 powered computer etc etc.

It still happily works on our peripheral computers but just wont fire up on the new main one.

We are not trying to network it....but would like to have it working on the  WINDOWS 7 machine which is the one my secretary prefers.

Thanks for any help
