Ran across this when installing Crystal to a Win7 computer. Thought I'd post to help anyone else who might be attempting this.

Other Adagio modules will pop up a warning telling you that you must turn off Window's "User Account Control" in order to install to a network drive. Crystal Reports doesn't give this notice though. So if you install all the other modules via the wksetup (wksetups don't show msg either), you won't see the msg at all.

If you don't turn UAC off before installing Crystal, you'll be unable to select any of your network drives as the destination. Same for the report tables selection. You'll only have local hard drives as options.

Turn off UAC, reboot, install Crystal, turn UAC back on (if desired) and you should be fine.
