I've been installing it with and without virusscanner/firewall/spyware and with the option "run as administrator", even downgraded my display driver to the ones supported by Solidworks... nothing seems to help?


I accompanied this post with the "Solidworks rx" log from, hope it helps finding the answer for everyone out there with the same problem.
