I'm currently running SolidWorks 2015 x64 on Windows 10 with an Educational license at my school.  I'm having issues on startup, and while running the HSM Express plugin.

If I open the program alone, there are no issues.  I can use it normally.  However, if I open the program by double-clicking on a .SLDPRT file, SolidWorks crashes with a 'SolidWorks 2015 has encountered a problem and needs to close' message.  I have been unable to find someone encountering a similar problem by scouring the internet, so here I am.

Additionally, I had been using HSM Express to generate G-Code before upgrading to Windows 10.  Since the upgrade to Windows 10, if I have HSM Express installed, SolidWorks crashes.

EDIT: Or rather, SolidWorks freezes in its loading screen, when attempting to load plugin HSMExpress.

I believe that the two problems I'm having are related, as they both occurred after upgrading to Windows 10 and SolidWorks 2015.  I have uninstalled and reinstalled both Solidworks 2015 and HSM Express multiple times, and tried launching Solidworks without HSM Express installed, always with the same result.  Has anyone encountered a similar problem before?
