Hello, I'm not sure what has changed but sometime yesterday I started to be unable to double click to open any file with SolidWorks through Windows Explorer. Now the only way to open anything is from withing SolidWorks' Open menu. I looked online and the only thing I found related to this was a dismissed message about opening read only files but I do not have that error message dismissed. This problem is only associated with opening SolidWorks files and all other programs work with double click just fine. SW2013 SP3, Windows 7 64bit.
