When I attempt to view a preview of a drawing in PDM (right click-> document info.-> view tab) I get and error that states "This file does not have a program associated with it for performing this action.Please install a program or, if one is already installed create annd association in the defualt programs control panel." What is the file type in this case? Sldwrks is already associated with slddrw, sldasm etc. Im running 2013 SP 1.0
