I have had some issues when I tried to keep both version (3.5 and 4.0) on the same PC. Try to use only once (you may need to clean any remaining registry key before installing Unity 4).

I second $$anonymous$$ryptos. I had issues with 3.5 and 4 on the same machine, $$anonymous$$e were different though, as 3.5 used to crash when trying to exit.

Hey i had the same problem actually, I uninstalled everything and did a clean install and seemed to work. I would try that last resort.
