This article was previously published under Q172454
IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, you should first make a backup copy of the
registry files (System.dat and User.dat). Both are hidden files in the
Windows folder.
SYMPTOMS
When you open the Sounds tool in Control Panel, you may receive an error
message similar to the following message:
An error occurred while windows was working with control panel file
C:\windows\system\mmsys.cpl
CAUSE
A registry entry for one of the sound schemes may be damaged.
RESOLUTION
WARNING: Using Registry Editor incorrectly can cause serious problems
that may require you to reinstall Windows 95. Microsoft cannot guarantee
that problems resulting from the incorrect use of Registry Editor can be
solved. Use Registry Editor at your own risk.
NOTE: For information about how to edit the registry, view the Changing
Keys And Values online Help topic in Registry Editor (Regedit.exe). Note
that you should make a backup copy of the registry files (System.dat and
User.dat) before you edit the registry.
The following registry key lists the programs that have sounds associated
with events:
Hkey_Current_User\AppEvents\Schemes\Apps
To identify and repair the damaged program registry key, follow these
steps:
- Click and rename one of the program key folders. For example, click
Hkey_Current_User\AppEvents\Schemes\Apps\Explorer
and rename it to:
Hkey_Current_User\AppEvents\Schemes\Apps\Explorer1
- Test to see if you can open the Sounds tool in Control Panel without
an error message.
- Rename the program key folder to the original name.
- If you received an error message in step 3, repeat steps 1-3 for the
next program key folder.
When you can open the Sounds tool in Control Panel without the error
message, you have found the damaged registry entry. Renaming the program
key folder to the original name corrects the damaged registry entry.
MORE INFORMATION
This behavior seems to occur most frequently with non-default schemes, and
is often associated with a problem during installation of the particular
program. The default schemes listed in the registry are: .Default,
Explorer, Mplayer, and SndRec32.
