I've been trying to register Comdlg32.ocx on my new system... quite the exercise in frustration! For a while, it wouldn't find the file, but I think I have worked around that problem by giving permissions to all users, since you can't Run As Admin for an .ocx file.
However, I'm geting a new error now:
The module "comdlg32.ocx" may not be compatible with the version of Windows that you're running. Check to see if the module is compatible with an x86 (32-bit) or x64 (64-bit) version of regsvr32.ocx.
My system is a 64-bit, so I'm pretty sure I would need the 64-bit comdlg32.ocx module. Does such a thing exist? Where can I find it? There are lots of sites out her with downloads for this module, but none seem to specify 32-bit or 64-bit.
