Error message when opening applications

[Guest]

When I try to install a downloaded program or even from a disc I get the
error message

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.

These programs have worked for me in the past. please help thanks.

You might want to take a look here:

This section towards the bottom will probably be of immediate
help:

1. Click Start, click Run, type c:\windows\repair, and then click
OK.
2. Right-click autoexec.nt, and then click Copy.
3. Click Start, click Run, type c:\windows\system32, and then
click OK.
4. Right-click anywhere in that folder, and then click Paste.
5. Right-click the Autoexect.nt file that you just copied, and
then click Properties.
6. Click to select Read-Only, and then click OK.
7. Repeat steps 1 through 6 to copy the Config.nt file.

Note You must enable Read-Only permissions or the files will be
removed after you restart Windows.

I have had the same problem. I took the programme to work today on a disk and
it worked ok on my work computer. It's something to do with non compatible
drivers but I'm not sure how to fix it. Would love to know the answer.
