I'm able to run it in Windows 7 64-bit successfully. You didn't say how you registered the ocx files, but I found that I needed to do it a different way rather than running the batch file to get it to work properly.
Try this:
Open an administrator command prompt.
CD to the directory where the ocx files are and type 'for %i in (*.ocx) do regsvr32 %i' without the quotes.
