Patch for Covert Ops?

I've installed RA95 with the patch to run the game on WinXP.

I'd like to install Covert Operations now, but when I try to install,
the CO ops disc just gives me a message that says, "Please run
setup.exe from the CD."

Placing setup.exe in Win95 compatibility mode does not help.

Is there a patch that will let me install the Covert Ops files?

If not, can I copy the CO files into the RA folder? If so, which files
should I copy, and where do they belong?

Thanks.
