16 bit Windows Subsystem queery

  MGZR 23:53 06 Feb 05


Can anyone tell me if I can get an old piece of software to run in Windows XP?

Everytime I try to install it I get the following error message: 16 bit Windows Subsystem.
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.
There is then a choice of Close or Ignore. Clicking Ignore just closes the application.
I have tried setting the computer to run the software in both Win95 and Win98 settings but had no luck.
I believe the software was originally for Win95.
So can I get it to run on XP or not?
Any help appreciated.

A. When you attempt to run a 16-bit application under NT, you might receive the following message:

Application popup: 16 bit Windows Subsystem : An application has attempted to directly access the hard disk, which cannot be supported. This may cause the application to function incorrectly. Choose 'Close' to terminate the application.

This error is typically the result of an invalid entry in the command.com, autoexec.nt, or config.nt files, which NT maintains for compatibility with 16-bit applications. To resolve this error, restore the default versions of these files from the NT installation CD-ROM by performing the following steps:

1. Run cmd.exe (go to Start, Run, and type cmd.exe).

2. Navigate to the %systemroot%\system32 folder by typing

cd %systemroot%\system32

3. Rename the current command.com, autoexec.nt, and config.nt files and append the word "old" to the filenames by typing

rename command.com command.comold

rename autoexec.nt autoexec.ntold

rename config.nt config.ntold

4. Navigate to the i386 structure of your Windows installation path (e.g., d:\i386) by typing

cd /d d:\i386

(the /d lets you change the drive and path at the same time).

5. Expand the original files from the NT installation CD-ROM by typing

expand command.co_


expand autoexec.nt_


expand config.nt_ %systemroot%\system32\config.nt

6. Restart your computer, and run your 16-bit application again.

Be careful and decide if the program is worth the effort.Your error is common for many of late but not all for the same reason.

Create restore point and recap to change back any changes to your system/files.

Downloaded the XP file fixer first and tried that. Hey presto it worked and the software is now installed and working.
Thanks for taking the time to answer my queery.
