Steven,

If Mark's suggestion doesn't work, make sure you have the latest version of VFP 5 and/or the VFP 5 run-time libraries on all the machines. The last version was build 415. You can check the VFP version using ?VERSION() from the command window. For the run-time find VFP500.dll in the windows\system directory, right-click it and choose properties. Click on the Version tab to see the build.

If you don't have 415, go to http://msdn.microsoft.com/vstudio/sp/vs97/default.asp and order or download Visual Studio 97 SP 3.
