Solve : My computer stopped running MS-DOS programs?

Answer»

I have a few MS-DOS programs that I use FREQUENTLY (a Bricks game and a lottery program). Until last week, I never had any trouble with them. Then last week I started getting an error message labeled "16 bit MS-DOS subsystem" It states "C:\Windows\System32\Autoexec.NT is not suitable for running MS-DOS or Windows programs". As far as I know, I haven't done anything recently that would change the way my computer handles MS-DOS programs. Nothing new downloaded or installed. Can you help me straighten this out?

My computer in a Compaq Presarion running Windows XP.http://www.microsoft.com/windowsxp/using/games/expert/durham_og.mspxWhy would it work for years, and suddenly stop working?Updates maybe........have you tried retro64 for brick games??demos??

or have a look here someone may have the FIX>http://www.iamnotageek.com/a/413-p1.php

Maybe another fix>http://www.softpedia.com/get/Tweak/System-Tweak/16-bit-MS-DOS-Subsystem-Error-Quick-Fix.shtml

I would advise anybody upgrading to winxp from win9x should buy the winxp full install disk and dual boot there system........sidewinder had a fix also for this by changing the attributes .....i think....This could be caused by an installation that ran amok. In any case, the file has been corrupted.

To fix run the following from the command prompt:

copy c:\windows\repair\autoexec.nt c:\windows\system32

After you copy the file, find it in Windows EXPLORER, click properties and lock it down by giving it a read-only attribute.

Hope this helps. Thanks ever so much!We aim to please......dont vanish....... you may no something we dont?......awaits sidewinder comments?I have the exact same problem.See reply #4 for the exact same solution.

perhaps the cd is in the wrong drive, try to put it in another drive (if you have two drives)i only have the one drive.i already installed it from the cd,it just wont playIs it a DOS game?

If yes, then the programs is trying to access the old MSCDEX.EXE cd-rom driver extensions.

You could overcome this with your personal CUSTOMIZED AUTOEXEC.NT & CONFIG.NT placed in the same fodler as the game. Add DOS SUPPORT cd-rom there.

Create a shortcut, and modify the advanced properties, point it to the alternate location of config.nt and autoexec.nt

Also, XP has a Compatibilty mode for older games. You will find this under the short-cut properties as well.
