If you try to register klog.dll on your system using regsvr32.exe, the following error is returned.

"Klog was loaded, but the DllRegisterServer entry point was not found..."

This is because klog.dll is not a COM DLL and as such, does not need to be registered.

To use klog.dll you simply need to ensure that it is in the same location as the klog.ocx that is calling it.
