Are you mounting exactly the same directory on drive C when you run the game and when you install the game? If you mounted c:\whatever as drive C when you installed the game, and then tried to mount c:\whatever\zork as drive C afterwards, that probably won't work. This is all in the 60 Seconds Guide.

I've installed dozens of DOS game CDs and havent had any problems yet. This is the first game to give me an issue.

Actually, this is probably similar to the problem you had with Mission Critical. Remember that?

If all else fails, Return to Zork is supported by ScummVM and will probably be effortless to get running there.

Hmm well I'm actually trying to run it without even mounting a directory for the cd drive.

I launch dosbox. Mount the cd drive as d: and install the game and run it and get that error. So just simulating an old machine, then I tried mounting d: as the cd image of the Return to Zork cd and have the same issue.

I'll give it a once over again and see if I'm making a mistake somewhere. Thanks again for the help!

This doesn't make any sense. You will always need to at least mount something as drive C and something as drive D. Following the aforementioned guide would be an excellent start.

Not sure why you're being so hostile 😀

Drive c is mounted as whatever dfend defaults it to, which is something something /.VirtualHD/ or whatever.

Drive d is mounted as the cd image ISO, which I set up using d fend.

So both drives are mounted properly.

I've added about 50 cd games through d fend with the same method and all of them have worked flawlessly.

Just curious if anyone has seen this error with return to zork

Unless you do it once following the guide, we will always suspect it's because of a mismatch of install and play mounts.
Your problem with "Mission Critical" proves, not everything will work flawlessly...

Sorry to respond to an old thread, but I saw this while looking up some stuff on RTZ.

IIRC, without the CD mounted, the game SHOULD default to the DOS version. Always. I ran into this problem running RTZ myself with boxer, even with the CD. It kept running the DOS version (difference being no sound, no video, etc). I don't think you can run the full CD version without mounting an image or the actual disk.

I myself have to figure out how to get an image of the game because I no longer have a CD rom in my computer, so my disk is useless.

If you're getting an error, it sounds like you picked a wrong setting.
