If you're going to copy the files from the first cd to your hard drive, you probably need to copy them all to your hard drive. But why did you copy them at all? What happens when you run the installer straight off the cd? I just now installed some software from cd-rom on ubuntu 11.04. I saw that Ubuntu had mounted the cdrom under the name CDROM (the disc was imaginatively mastered :-), and I'm used to using the commandline, so I did cd /media/CDROM wine setup.exe For a multidisc app, you may need to instead do cd /media wine CDROM/setup.exe (substitute the right disc name for CDROM) otherwise the disc might have trouble ejecting because the mount directory is in use. Also, what's that app's home page? What does 'wine --version' say?
