where <n> is a number between 0 and 23.

Causes for unexpected errors include incompatible terminate-and-stay- resident
(TSR) programs, low BUFFER settings, and incompatible virtual device drivers.

MORE INFORMATION
================

The following numbers represent specific Unexpected DOS Errors in Windows 3.0.
An asterisk (*) indicates that the error is trapped and handled by Program
Manager (PROGMAN.EXE).

   *0  Out of memory
   *2  File not found
   *3  Path not found
   *5  Attempt to dynamically link to a task
   *6  Library requires separate data segments for each task
  *10  Incorrect Windows version
   11  Invalid .EXE file
   12  OS/2 Application
  *13  MS-DOS 4.0 application
   14  Unknown EXE type
  *15  Attempt to load an EXE created for an earlier Windows version
  *16  Attempt to load a second instance of an .EXE
       containing multiple, writeable data segments
  *17  Attempt in large-frame EMS mode to load a second instance of an
       application that links to certain non-shareable DLLs already in use
   18  Attempt in real mode to load an application marked for protected

Unexpected DOS Error 1 can occur with third-party video drivers.

Unexpected DOS Error 2 can occur if you install Time$heet Professional on a
system with the Certus NoVi TSR program loaded.

Unexpected DOS Error 5 can occur when virus-scanning software is running (noted
with VDEFEND) or if the buffers= line in CONFIG.SYS is set low (that is, less
than 10).

Unexpected DOS Error 6 can occur if you run Time$heet Professional on a system
with the Certus NoVi TSR program.

Unexpected DOS Error 11 can occur if you use a third-party video driver.
Resetting Windows to a default video driver (such as standard VGA) corrects the
problem.

Unexpected DOS error 11 can occur if WINOA386.MOD is corrupted.

Unexpected DOS Error 13 can occur under Windows 3.1 if you try to run a program
created with Microsoft C version 7. No resolution is available.

Unexpected DOS Error 13 can occur under Windows 3.1 if you try to run an
MS-DOS-based terminal emulator program (for example, KEA's Z-Stem).

Unexpected DOS Error 14 can occur under Windows 3.0 if you run Borland Paradox
version 4.0.

Unexpected DOS Error 21 can occur when you try to run Math CAD for Windows,
version 4.0. To resolve this problem, obtain Math CAD's Fax #2000.

If you experience DOS Error 21 running Microsoft Works, you may be able to
resolve the issue by increasing the MS-DOS environment size to 2048 bytes. To do
so, add the following line to the Config.sys file and then restart your
computer:

       shell=c:\command.com /p /e:2048

Unexpected DOS error 23 can occur when you run Microsoft Golf.

Unexpected DOS error 23 can occur when you try to start an MS-DOS prompt or an
application and WINOA386.MOD is missing from the Windows directory or the
Windows SYSTEM subdirectory and is not in the path.

Unexpected DOS Error 23 can occur, along with the message "Cannot find
WINOLDAP.MOD," when you try to set up Microsoft Mail 3.2 extensions for
Workgroups after you start Windows for Workgroups with the /D:T switch.
