All my UG files have been converted to SolidWorks

I have any end users who uses UG and SolidWorks from the samepc. He uses UG much more than SolidWorks. I installed SolidWorks2009 on his pc and now all his UG files have the SolidWorks icon onthem instead of the UG icon. Does anyone know how to fix this otherthan removing SolidWorks completely from his pc. I went back toSolidWorks 2008 thinking this would help but all files showup asSolidWorks filesSolidworksParts And Features
