​​SolidWorks 2015/16 SP3 installation issue- after downloading from the customer portal the install fails/crashes several times during installation. It Blue screens at various stages during install process. I have tired uninstalling 2014 version first and deleting temp files but it makes no difference. We have 20 well speced 64bit machines and it has done it on more than half. It can take 5-6 goes before it installs properly. Please advise.
