Vista 16-bit MS-DOS Subsystem error

Messages

I'm getting and 16 bit MS-DOS Subsystem error.

C:\Windows\System32\command.com config.nt
the system file is not suitable for running MS-DOS and Microsoft Windows Applications
Choose 'Close' to teminate the application.

I've seen this error on XP before but never on Vista until now.
The solutions for XP don't work because those files are already in the System 32 folder.
I've attached an image of the error.

I'm running Vista Enterprise edition. It is a 32 bit machine so it should be able to run 16 bit apps
I just want to use COMMAND.COM instead of cmd.exe

Any help would be greatly appreciated.

Welcome to the forums!

What 16 bit program are you trying to run? Does it use the CD Rom drive?

There may be a solution available, just need to know more about your situation.

Thanks for the welcome and your reply.

The program I'm trying to run I installed on my CPU, its not on a cd-rom. I'm trying to run the app without using things like DOSbox. I know 16 bit apps should work. But when I try to run command.com it won't execute. So right now my machine won't run any 16 bit apps. I did a test with Visicalc and that didn't work either.

I've been doing some more reading about this issue. The advisors say that 16 bit programs won't run in Vista. The recommendation is that you download and install Virtual PC, which runs other OS's and they say you can run Dos 3.3 in the VPC, then run your 16 bit program. Or as you mentioned DOSbox is an option.

I'll also open this up for input from our admins and mods to see if they have any suggestions to assist you.

Thanks for the suggestions. Some of my friends have Vista Home edition. They are able to open up the command.com window. The process I'm using is open the run command window and type command.com. It works for them, I was just wondering why mine doesn't work. I can't even get the window to open up. Does it work on your machine?

Hi,

I have the same problem when launching any 16 bit installs on very machine in my environment. Did you find a solution? I know this works on a vista build straight out of the box but can't workout what has changed in my environment to cause this. Any ideas?

Hi & Thanks,

All these files exist and i've also replaced them in case of corruption. Also this issue occurs weather logged in as an administrator or standard user.

I believe it may be a similar issue to this article as changing the TMP location to c:\windows\temp partailly reolves the issue but i don't believe it be a practical resolution. "Config.nt The system file is not suitable for running MS-DOS and Microsoft Windows applications" error message when you try to run a program in Windows 2000

Hope this helps

Can you attach your config and autoexec files?

EDIT:
Have a look in your command.com properties.
Make sure that in program tab/advanced, the path to autoexec and config are rights.
Make sure in security that users have the execute and read rights
Make sure screen is not set to full screen
Memory should be set to auto

I assume these files are not available in x64 bit versions?

I would like to add that the choice of using DOSBox or Virtual PC depends whether ur 16 bit app can handle processor speeds in excess of 1 GHz that all of us have today.

For example, I have managed to get "The Need for Speed SE" 32 bit version runing at full speed in Virtual PC 2007 with Windows 98 SE as the guest OS. It runs great without any hicups which some people have experienced when they tried to run it directly in Windows XP.

On the other hand, the DOS game "One Must Fall 2097" can not cope up with the processor speed and runs way too fast. It seems as though the game is runing at least 200% faster than its supposed to run, so I checked the processor speed from inside Virtual PC 2007 with CPUZ and found out that it showed my real CPU speed, which prevented most of my old DOS games from running causing the infamous "Runtime Error 200" which is caused when the processor speed is too fast for the program.

So, in short: Try your 16 bit app in Dosbox first since it is not much of a hassle to install compared to Virtual PC 2007, and check the performance. If you are satis fied, stick with it. If you aren't, you'll have to go through the painful procedure of installing Windows 98 SE in a Virtual Machine using Virtual PC 2007.

The only con that I see in Virtual PC is that it does not prvide a way to throttle CPU speed according to the guest OS, which causes the above mentioned problem.

Hope this helps!

P.S: Here's a screen shot that I e-mailed a friend of mine who wouldn't believe that I had gotten NFS-SE to run at full speed:

Yanno, there used to be a nice little app to slow down the processor speed for old 16bit games when I was on XP - Let me look around and see if I can find it - it is ancient, but then again, I have some 10 year old apps on CD still....

I might have it as well! Is it CPU Killer?

Its what I use inside The Windows 98 Virtual Machine to slow things down. But I use the old version 2.05 which is shareware. The website has a newer version:
