when you run in dosbox there is no NTVDM.EXE

you might want to try the following 2 things.
Try no sound or soundblaster

Secondly be sure to have installed the game from within dosbox.

Don't configure the game to use GUS.

If your using DosBox http://dosbox.sourceforge.net then there is no NTVDM.

Did you install the game straight off of the CD?

Hi there,

@Qbix:

As I said, it's not possible for me to even access the sound setup program successfully.

I've just attempted a re-install from within DosBox, and received the following error message:

"W_InitFiles: no files found"

@DosFreak:

The Gravis Ultrasound message is just a standard dialog box that appears during the setup process containing information for GUS users, and doesn't affect the setup in any way (other than being annoying)

Yes, I installed the game directly from the CD.

I've just attempted a re-install from within DosBox, and received the following error message

Please start off with a clean installation of the 0.72 release of dosbox,
especially a default dosbox.conf
Set up your mounting (cdrom/hd) in the autoexec section, and post the
exact settings here. Proceed with the installation of the game and,
if there still is an error, post the exact message.

Hurrah! Success!

@wd:

A clean DosBox installation seems to have done the trick!

The game is now up and running 100 percent!

Many thanks to all who contributed! 😀
