Benoit,
The only other thing I can think of is do you have the VFP runtime installed on the second computer? I would think your ofox object will need the VFP libraries just like an EXE would.

I think it has the right path because when I call Excel from my application, Excel starts and create my FoxPro object : oFox ...When I do oFox.DoSomething() , I have the error message.If I click on debug button, I can see my VBA code and the line where the error is. At this moment Excel is open but my code doesn't work !
