I have SW 2014 SP1 DVD, with proper S/N. However, sometime during the install process, my computer crashed. This happened several times while attempting to install Solidworks 2014. I cannot for the life of me figure out why my computer would crash. My computer has up to date video drivers, 7Gb of ram, 64 bit Windows 7. I know that during install process it seem to take a very long time to install at 3%, then my computer would freeze/ hang up. I would get some kind of blue screen. That is as far has installtion would get. There must be some trick to installation.
