I'm trying to install this game. I go to the directory, try to install and it tells me to do the following.

To setup UFO, Enemy Unknown.

Change direction to [note: yes, this is just an empty space] and then enter
CDSETUP followed by your CDROM drive letter.

For example CDSETUP D: or CDSETUP E: etc...

I try all manner of things, but it never does anything -- just goes back to the XCOM directory. What do I need to do?

Is there a guide to installing this game on a mac anywhere? I tried searching for a couple different things but no luck.

Thanks
