My customer asked me for help when he tried to open Event Viewer, the following error appears and the Event Viewer does not launch:

Snap-in failed to initialize.
Name:Event Viewer
CLSID:{975797FC-4E2A-11D0-B702-00C04FD8DBF7}

What should you do? Just run the following command in command prompt:

REGSVR32.EXE %WINDIR%\SYSTEM32\ELS.DLL

If you get the following error message when you run the above command, then expand a copy of the file from the Windows XP CD, or from the Service Pack files source path. Or get a copy from other system. Put it in C:\WINDOWS\System32\. This should do the trick.

LoadLibrary(”C:\WINDOWS\System32\ELS2.DLL”) failed - The specified module could not be found.
