I know I need to have the setup program register my OCX controls, do I also need to have the setup program register the support DLL's? Some of the DLL's that need to be distributed according to the OCX vendors are:

MFC40.DLL
MSVCRT40.DLL
MSVCRT20.DLL
MSCANS32.DLL
STORAGE.DLL
TYPELIB.DLL
OLE2.DLL
OLE2DISP.DLL
OLE2NLS.DLL
COMPOBJ.DLL
COMDLG32.DLL

Do I just have setup copy these files to the WINDOWS\SYSTEM directory (overwriting only if older version) without having REGSVR32 register them?

I know for the most part most of these files will already be on the users machine, but I cannot know for sure since this application is being distributed to over 600 sites.

Any help along these lines would be greatly appreciated. I just didn't want to leave something out before distributing to all these sites.

TIA,

James
