software install problems

[Guest]

A few software programs I've tried installing on my Windows xp will give me
an error pop-up that says

16 bit Windows Subsystem
C:\Windows\System32\AUTOEXEC.NT. The System file is not suitable for running
in MS-DOS and Microsoft Windows Applications. Chose close to terminate the
application.

The software programs that I'm installing say that they are Windows XP
compatible, so I don't understand what's causing this pop-up, and why I can't
install these programs.
If anyone can help me I'd really appreciate it... some of the software I've
paid money for and can't get a refund.

Thank you,
Romney

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"
