not really on topic, but I tried it on vista32bit and it just works fine without DOSbox at all...

Menu Manager is a compiled BASIC program that apparently does an OPEN "NUL" command. DOSBox does not fully support using devices in the manner that some BASIC programs use them.

You can read more about the issue in this thread, where QBix has provided an alternative build of DOSBox that might allow the program to work without the error. Please remember that DOSBox's primary goal is to support games, and support for other kinds of applications is not a priority.

They thanks for the info...I read the other thread but the other version he created I could not find when I clicked on the link? Any suggestions

I guess it's not available now... perhaps it was a limited-time offer. 😀

The program will work if you run it under a real DOS booted in DOSBox (or other virtualization software for that matter).

I think I deleted it during a clean up.
Does this dmenu also try to set the attributes? as I think that detection thing was fixed ages ago.

Yep, the error results from setting the attributes on the device with unsupported IOCTL function 1. I think BASIC typically does that when you open devices for I/O. Faking success of the function seems to allow programs like this one to work, but dunno what side-effects it could cause.

the unknown side effects was my main reason not to add it directly to the CVS.
might be a candidate to go into a beta build oneday.

So....I run DosBox and then within DosBox I run a DOS program?? I think I'm confused

No you run DOSBox and then install MS-DOS (or other DOS variant) inside of it.

or you use another VM program such as Virtual PC or Vmware and install a DOS variant in there.

OK cool but I tried searching for a DOS program but I don't know what specifically I'm looking for

I thought you already had the program? Do you mean the OS?

You need MS-DOS or FreeDOS if you are looking for the OS.

As for the program you'll have to figure out what you want to run. I can't help you there.
