Old program will not install now

[Donald D.]

I have an application on my C: drive (FAT32) that was installed a couple of
years ago. Since then, I have downloaded some WinXP patches. Now when I
boot the CD and hit install, it spits out 'C\WINDOWS\SYSTEM32\AUTOEXEC.NT
The system file is not suitable for running MS-DOS and Microsoft Windows
applications.'

If it is one of the ms patches, which one is it that I can uninstall and
resolve this?

Could it be the controls.dcu?

Seems to be an epidemic lately....

This can be caused by a trojan.

Get rid of the trojan.

Update your antivirus software and run a full system scan.

Copy the autoexec.nt file from C:\Windows\Repair to C:\Windows\System32
And set Attributes for autoexec.nt to Read-only.

Or %systemroot%\Repair to %systemroot%\System32

Read-only
[[Specifies whether this file is read-only, which means that it cannot be
changed or accidentally deleted.]]

1. Right click the file.
2. Properties.
3. Select: Read-only.
4. Click: Apply.
5. Click: OK.
