I get this error when attempting to uninstall a program or install a program
with a .exe extension.

16 Bit Windows Subsystem
C:/WINDOWS\SYSTEM32\AUTOEXE.NT. The system file is not suitable for running
MS-DOS and Microsoft Windows applications. Choose "Close" to terminate the
application.

Operating system is Windows XP w/ Service Pack 2

Thanks,

Lou

Error message when you install or start an MS-DOS or 16-bit Windows-based
program

Replace the standard version of autoexec.nt/config.nt by copying a backup
copy
located in %windir%\repair\ to %windir%\system32\
(NB: %windir% is typically C:\Windows)

Also can be caused by a Trojan installing a file windupdater.exe and
creating registry entries for that file.

AVAST (free antivirus software) can be the cause if SP2 is installed:
