When I initially tried installing SolidWorks on Windows 10, the installer quit very early (only 1% complete) with an error message that installation of Microsoft components failed. What I found out is that Windows 10 already has those components installed, so when you get those error messages from the SolidWorks installer just skip to next step and SolidWorks will install (and work properly). I think I received three error messages. Hope this helps others trying install on Windows 10.
