How to troubleshoot missing or damaged files.

Whenever I try to load a new program and sometimes when I try to open an existing program I get an error message that states:

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.

You also have the option to ignore, but either option freezes the application and you have to use the task manager to end task.

I tried to follow the instructions given by the microsoft website, but I am either doing something wrong or it's just not working. Any help you can offer will be appreciated!

Thanks,

Debby

You maybe able to resolve this issue by:

expand CD-ROM Drive Letter:\i386\command.co_ c:\windows\system32\command.com

Type "Exit" to end command mode.

5 Start or install the program

IF THE ISSUE IS NOT RESOLVED, GO TO THE NEXT STEP.
