i dunno, it installed just fine with the full installation for me
i don't know if it could change anything, but i am using
power iso (free version works fine, don't have to buy) to mount my cue image (cue not bin!) then i mount the virtual power iso drive inside dosbox and install it from there. if your error persists, you could try creating a thread in
troubleshooting, much more people look in there, this is a sub sub forum of a specific game btw
