The reason of your problem is probably simple: Windows/system32 is not a folder where the engine should search for engine plugins. Set the plugins directory to a different folder.

From the manual:

"On startup, the engine scans for plugin DLLs in the current folder and in the PLUGINDIR folder. This can lead to a slow start when the folders contain lots of DLLs that are no engine plugins - for instance, when the engine is used as a screensaver and started from a Windows folder. If a DLL crashes on opening, the engine crashes also. Thus make sure that PLUGINDIR is set to a folder that only contains engine plugin DLLs."
