The VFP COM component is multi-threading, and I have the VFP7 and C++7 run-time libraries installed on the machine. The fact that is works on my machine must mean that I missing a needed DLL or something is corrupted on the other computer. Are the VFP7 and C++7 run-time libraries the only required files needed for VFP7 COM objects? I used InstallShield (limited version) that came with VFP7 to distribute the libraries to other machine.

Thanks for your help!
