Thanks George,

It actually is an FLL I probablly should have made mention of that more clearly, I specifically have written it for FoxPro in C++, I just haven't changed the file extention, though in hopes that that might be what the problem is I have changed the extention and have recompiled the program and have tried it again on the test box I've been using, and still it works on the machines with FoxPro and not on the machines without. This is the only problem however, it works just fine in every other aspect and I have copied over the VFP6R.DLL and VFP6RENU.DLL and have registered some other OCX files that my program uses, everything seems to work except this and I can't figure out why... -Bryce
