I have added DZOCX32.OCX, DUZOCX32.OCX, DZSTAT32.OCX and OC30.DLL as self-registering and have added all the other files they list to be copied to the Windows System folder.

Try registering them manually via RegSvr32 or in your code programmatically register it via DLLRegisterServer/DLLUnregisterServer.

While I'm not positive, marking the control as SelfRegistering causes the installation program not to actually register the controls. It thinks the clients using the control (VFP, VB, etc.) will take care of that via calls to DLLReg...

HTH.
