I am getting an error message when I try to run certain programs that I have
had no problem running in the past the error is
C:WINDOWS\SYSTEM32\AUTOEXEC.NT. The system suitable for running MS-DOS and
Microsoft Windows applications.
It also has two choices "close" and "ignore" but neither one alows the
program to launch.
thanks

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.

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)

Start>Run and type in this without the quotes:
"cmd /c copy /y %windir%\repair\autoexec.nt %windir%\system32"
