I get this when I try to run any program that needs ms-dos to work... I use windows xp, and have looked at some sites to get it to work, but no luck so far...

16-bit MS-DOS Subsystem
path to the program that you are trying to start or install
C:\Windows\System32\Autoexec.nt The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application.

I had this problem here at work. After you run anti-virus and spyware applications, you need to get a good copy of the Autoexec.nt file. In my case it disappeared off my computer and we had to put it back. Definitely created by a virus that got through.

Maybe the trouble your are experiencing is because your DOS app needs to open 'x' quantity of files. This number of files is established in the autoexec.nt file so you must increase the value of Files to a number near 254 the maximun value.
After you change this it is not necesary to reboot, you can run your DOS app.
