compatibility wizard problems

[Duane Broadwell]

I have tried everthing in trying to use the compatibility wizard , and the
control panel and the Windows Explorer when installing some pre 1997
programs. The program installed ok on my 98 but not on my XP. here is what I
see.A window opens that says 16 bit windows subsystem- then below that it
says. C:\windows\system32\autoexec.nt The system file is not suitable for
running ms-dos and Microsoft Windows Applications. So , what can I try next
.. anyone have any suggestions. Duane

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.

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)

note:-
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:
