Hello, I just upgrade to 4.2 from 4.1.5 and now I cannot get Unity to work at all. Every time it loads it crashes before the editor can come up. Scenario: This morning I went to the unity website and downloaded 4.2.0. Download came down fine. went to install it and just like every upgrade I've done before unity automatically removes previous version then installs the new version. Once install had completed it prompted to upgrade my project. I agreed then nothing happened. Checked task manager and there was no unity instance running. Started unity again and it says a problem caused the program to stop working correctly. Restarted computer, tried unity again, got same error. Uniinstall/Re-install, try again, same error. Un-install, restart computer, re-install, try again, same error. Un-install, remove all temp file traces and registry traces, restart, re-install, try again same error. Computer: Lenovo Yoga 13 Core i7, 8GB RAM, 256 SSD, intel 4000hd graphics I am not sure what to do. If anyone has any ideas please let me know.
