>I have created a DLL in Visual Foxpro 6.0 and I call the DLL from an Excel 2000 VBA Application, what DLL (or DLL's) should I include when I try to run the Excel-program from a pc without (Visual) Foxpro. Is it enough just to include the created DLL from Visual Foxpro and register this DLL ????

No this it not enough.

Use the setup wizard to create a setup programm, the wizard will add needed runtime files.
