solidworks query - clsid
i needed help. i have been working on a vc 6  project that has to work on solidworks. i have been able to create an instance using cocreateinstance and have been sucessfull in getting mass properties from solidworks api.
but i needed to know if solidworks is installed on a particular machine using the clsid.
but i done know how to do that.... if there any way using the clsid that i can find out if solidworks is installed or not. if it is not installed then i need not to do "cocreateinstance".
could u please help in telling how to do this....
