not that it will help much
did you try
mount a /mnt/floppy -t floppy ?

I tried 'mount a /mnt/floppy -t floppy' but still the same problem.

Isn't there anyone who got this game running?

It's running fine but i didn't install it.

You run it from the floppy?

No, as it was preinstalled.

For your floppy problem: did you try copying all files into one
directory? Works sometimes, even if the installer wants a
2nd disk in the end, but for a few games all necessary files
are already installed.

Yes, tried that and got the same error. Although I didn't try to run the game afterwards. I'll try that.

Are you installing from the original floppies? Many times I have seen a similar error and the installer was checking the volume label of the floppy. If it was a floppy that had been zipped for storage, be sure to use the -$ switch when unzipping to a floppy to restore the volume label, that is if it was zipped properly with the -$ switch to save the volume label. I think X Wing might have been one that checked for the proper volume label during installation. Access Software did as well with most of the Links products and GEM was another I remember that used that method too.

Yes, I'm installing from the orginial floppies.

I was able to install the game like this:

1. Copy all the files on the floppies to a directory.
2. Make sure the content of disk.id is:
X-Wing Space Combat Simulator
1.0
X-Wing Disk 5
3. Run install.exe from DOSBox

I just stumbled upon this thread in search for this problem. Lievens solution works.

I'd like to add, that you have to mount the directory (where all disks were copied to) as drive letter C: or D: and so on, but not as A: or B:. If you try it with A: or B: (which were the standard for floppies back then), the X-Wing installer asks you to swap the floppies, which will not work. If you choose e.g. D:, then the installer will not ask you to swap anything but will just install the whole thing in one run.
