======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows versions 3.1, 3.11 
 - Microsoft Windows for Workgroups versions 3.1, 3.11 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you try to add drivers in the Drivers section of Control Panel, Windows
generates the following error message

   Driver Error: Cannot load <driver name>. The driver file may be
   missing. Try installing the driver again or contact your system
   administrator.

where <driver name> is one of the following:

   Intel Indeo (TM) Video Board
   Timer
   MIDI Mapper
   [MCI] MIDI Sequencer
   [MCI] Sound
   Sound driver for PC Speaker

CAUSE
=====

You can receive this error message when you attempt to install drivers from
Windows 3.11 or Windows for Workgroups 3.11 into Windows 3.1.

This error can also occur if one of the following conditions exists:

 - MMSYSTEM.DLL is corrupted or missing from the Windows SYSTEM subdirectory.

 - LZEXPAND.DLL is corrupted or missing from the Windows SYSTEM subdirectory, or
   is the wrong version.

 - EXPAND.EXE is corrupted or missing from the Windows SYSTEM subdirectory, or
   is the wrong version.

RESOLUTION
==========

You can correct this problem by expanding MMSYSTEM.DL_ and LZEXPAND.DL_ from
your original Windows or Windows for Workgroups disks using the following
syntax:

   expand a:<filename>.dl_ <windows
   drive:directory>\system\<filename>.dll

For example, if you are expanding MMSYSEM.DL_, your original Windows floppy disk
is in drive A, and your Windows directory is C:\WINDOWS, type the following at
the MS-DOS command prompt and then press ENTER:

   expand a:mmsystem.dl_ c:\windows\system\mmsystem.dll

EXPAND.EXE does not need to be expanded from the original Windows disks and can
simply be copied to your Windows directory.

Use the following table to determine the disk on which MMSYSTEM.DL_ is located:
