My routine assumes that all required OCX's (or DLL's) are correctly installed. However, you could include these files in your Exe and (if not already installed - or uninstalled) then copy them to any suitable folder, then conditionally register them programmatically using:

RUN REGSVR32 .../SomePath/mswinsck.ocx /s

The /s suppresses any message boxes.
