>Did they say what would happen if you just make the executable read only on the network?

No, they went off on some line about dll libraries and registry settings. This system that I am getting the error 1104 ran fine when it was vfp 3. We have a workstation setup that installs a dummy file inorder to force installing the libraries and etc.. on the workstations. Microsoft tech support told us how to do this when we started with VFP 3.
