Win16 error message

[Guest]

I keep getting this message when I try to uninstall a
program (specifically, AVG 6.0):

"Win16 subsystem was unable to enter protected mode,
dosx.exe must be in your autoexec.nt and present in your
path."

What does this mean, and how do I fix it?

Hi,

Thanks for the mention of AVG, that is a great start in troubleshooting this
issue.

Something has added a line to it which should not be there.

Edit it with NotePad. It should contain - apart from many comment lines
starting REM - just

REM Install CD ROM extensions
lh %SystemRoot%\system32\mscdexnt.exe

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

REM Install DPMI support
lh %SystemRoot%\system32\dosx

And possible SET or PATH lines:

Remove anything else by turning it into a comment, adding REM and a
space as shown in the above. And please note what they were and report
back - this is happening a lot and I would like to find out *what* has
got added.

Please provide feedback if you can. It would be greatly appreciated and
will help others.

Check the windows\system32\autoexec.nt file with NotePad

Look for

REM Install DPMI support
lh %SystemRoot%\system32\dosx

and be sure it is present and that no REM has been added before the
second line. Second, check that the dox.exe file is in fact in
Windows\system32

If those are OK, check your program by r-click and Properties, on the
Program page click Advanced and make sure that the Autoexec filename is
correctly set to find this file:
%SystemRoot%\SYSTEM32\AUTOEXEC.NT
