Quick question; I keep on being told that I can't run a program because "The
system files is not suitable for running MS-DOS and Microsoft Windows
applications." How do I fix this>

I've tried changing the compatability options of the program, but it doesn't
seem to help matters.
 
Hi,

Create a new autoexec.nt file and save it to the \windows\system32 folder.

Click start/run and type notepad, then click ok. Copy/paste the below code
into it (instead of typing it in to prevent errors), then click file/"save
as". Navigate to the C:\Windows\system32 folder, change the "save as file"
type to "all types" and name the file autoexec.nt, then click save (if
prompted to overwrite the existing one, do so).

@echo off
lh %SystemRoot%\system32\mscdexnt.exe
lh %SystemRoot%\system32\redir
lh %SystemRoot%\system32\dosx
SET BLASTER=A220 I5 D1 P330 T3

Reboot when finished. This usually fixes it, but you will find further steps
here if it doesn't:

Basically, you will have to expand new copies of command.com, autoexec.nt,
and config.nt to the system32 folder from the WinXP CD or I386 folder on
your hard drive, or copy them from the C:\Windows\repair folder to the
C:\Windows\system32 folder. Sometimes, you need to create new ones and
overwrite the existing ones - the method is described in the article.

Hi

Is there a reference to a autoexec.nt file in the error message?

The autoexec.nt problem is most likely caused by a worm or if you have
WinXP SP2 and AVAST (antivirus software) installed, it also can cause
this error.

You can put back the standard version of autoexec.nt/config.nt by
copying a backup copy held in %windir%\repair\ to %windir%\system32\
(%windir% is typically C:\Windows) instead of using the procedure in
the KB article above.


Could be caused a trojan or something similar, e.g.
TrojanDownloader.Win32.Dia.a, more about this here:

Also, AVAST (antivirus software) can be the cause if you
have WinXP SP2 installed:
