The installation CD appears in .wine/dosdevices/d:, which is a link to a block device and has brw-rw---- permissions. There are actually 2 setup.exe files on the installation CD. One is a 40kb DOS/Windows executable which returns the 'Setup cannot find the necessary files' msg when opened with WINE. It's -rw-r--r--. The main setup and data files are in a directory on the CD called 'files'. There seem to be 3 installation files here: setup.exe (103kb), iassist.exe (248kb) and instmsiw.exe (1.7mb). All are shown as -r-x------. The warning msg you point to refers to the 'files' setup.exe. Nothing at all happens when I try to open any of these with WINE, i.e. no read of the CD (no whirring noise from the CD drive).
