>When I compile a MTDLL on a machine, the compilation automatically registers the object. What if I want to register that object on another machine, what to do. I know it's probably been asked a thousand times before, but please....

just run the following command (from the Start menu - Run..., or from the prompt):

RegSvr32 c:\yourdir\yourCOM.dll

(replace the c:\... for the right path for your MTDLL)

of course, you must have the VFP runtimes on the machine in order for the registration works.
