Why does my SolidWorks crash when I try to run a macro? Daniel Lyon May 28, 2014 16:29 We were trying to run a CAMWorks macro & as soon as I hit play it crashes SolidWorks. What's the cause? Have more questions? Submit a request Comments Daniel Lyon May 28, 2014 16:30 It seemed a bad install of Visual Basic. Go to your solidworks downloads folder where you installed SolidWorks from & browse to SolidWorks 20XX x64 SP03\prereqs\VBA. Reinstalling the VB pre requisite fixed the problem.
