16 bit Windows Subsystem error -- FIX

[robboll]

I was getting the following error whenever I tried to install an
earlier version of windows application:

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.

I also got the error when entering 'Command' in the Start->Run Open:
dialog.

My fix:

I noticed that I was missing the file: C:\WINDOWS\SYSTEM32\Autoexec.nt

I created the file in the System32 directory and edited it to include
the contents:

lh %SystemRoot%\system32\mscdexnt­.exe
REM Install network redirector (load before dosx.exe)
lh %SystemRoot%\system32\redir
lh %SystemRoot%\system32\dosx

That fixed it for me. Hope it helps!

Not to rain on your parade, but you could have just copied it back from
the Windows\repair folder.
