Any ideas why SolidWorks is Crashing

Hi can anyone suggest what may be wrong with this users installation? He says he has installed solidworks on 6 PCs so far with no issues until he gets to this one. It appears to install fine but crashes when he tries to load it.

Its SWx 32bit on a 32bit machine. I've received his RX file and can't see anything wrong with his system. I'm all out of ideas by this stage.
