C:\windows\system32\autoexec.nt

I am having problems installing a couple of different programs and games. I get an error message ["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.] It gives me two boxes, one 'Close" one 'Ignore', either button closes the Installer package. All the apps and games are proper ones that run under XP on other comps, can anyone shed any light on what might be wrong with mine? All tries have failed, they are all 'Autorun' installers, I have tried also to run them without the autorun, also in 'Safe Mode' and from 'Explorer', 'My Computer' Run as Windows '98, '95, NT- everything, all to no avail. Please suggest something if you have any ideas as I am all out of patience with this dilemna.

Thanks in advance

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.​

This issue may occur if one or more of the following files are missing or damaged:

• Config.nt
• Autoexec.nt
• Command.com
​

RESOLUTION

1. Insert the CD into the CD drive or DVD drive.

2. Click Start, and then click Run.

exit​

5. Start or install the program. If the issue is resolved, do not complete the remaining steps. If the issue is not resolved, go to the next step.

files=40​

Thank you for your response, I must seem very thick, but which CD do I put in XP or the Program, if XP will I have to put it in for everyone of them? I forgot to mention these are all progs that run under XP every other computer I try them on, they are supposed to run with XP, also I don't have any problem running most apps and games, just the ocassional ones.

Thanks Les

 

The XP CD. No You don't have to do it for every prg. Just make sure you that the files to Read Only or else they will be deleted when windows restarts.

 

Thanks again, I will try and fix it now, so I will log off, if I have any further trouble I will let you know.

Thanks heaps for your help.
