>In an application, I am distributing comctl32.ocx. I have also included comctl32.dll in the setup. Is there really a need to have the dll file included as well. Or, comctl32.ocx is running by itself?

Comctl32.dll looks like it is installed in the system by something other than VFP. We have several machines that do not have VFP, but do have Comctl32.dll
As best I can tell, you do not need it to distribute/run the ocx.
