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:
