When I try to run a program I receive the following message.

'the Win 16 Subststem was unable to enter protected
mode, DOSX.EXE'

From what I have read on both the Microsoft & Symantec web site it seems
that this has something to do when you try to run a program using Windows
NT. I'm not using NT but XP PRO. How does one fix this problem? I have
even seen on Symantec's web site how to fix the problem but it entails
adding lines to the registry for files that aren't even on this machine.

Could I try system restore to set the system back a week or would that not
work?
 
1. Open Notepad. (Start/All Programs/Accessories/Notepad)
2. In notepad: File/Open (select "All Files" at the bottom)
3. Navigate to..My Computer/C Drive (c:)/Windows/System32
4. Locate the file "Autoexec" (NT File) and double click on it.
5. after the "@echo off" on the top line, start a new line beneath it by
pushing <ENTER>
6. type in: c:\windows\system32\dosx.exe
7. Then select File/Exit and when it asks to save, click on "Yes"

Then Reboot and try your program again.
 
I've tried this but it doesn't make any difference when I reboot. I still
can't install the new program because I still get the same message. Any
other ideas?
 
Do you have dosx.exe & autoexec.nt in \windows\system32 directory? Or
was it somehow deleted or moved?
Here's a link to the MS knowledge base:

AND

http://support.microsoft.com/default.aspx?scid=kb;en-us;150420

AND this one (which may be more applicable to you since it applies to
Windows 2000)

I realize these links apply to the NT O/S, but should help in your
diagnosing and fixing the problem.

Hope this helps. BTW: you're trying to run a 16-bit program in XP? Is
your file system NTFS? or FAT32? Is there an upgrade to your program?

---------------------------------------------------------
 
The autoexec.nt file is in the system 32 directory. I can't find dosx.exe
in the same folder. If it's really missing how do I get another copy?
 
I have had another look & can now find both files in the system 32 folder -
that is autoexec.nt & dosx.32. I still get the same message when I try to
install the program however. Should I have a similar line in there
referring
to 16 bit since that seems to be what the reported error message was about?
