Unity 3 Crash on Start Up (Windows Vista)
So I get past the image of the soldier, and as soon as Unity opens it says:
(Image of Circle with X inside of it) "Runtime Error!
Program:C:\Program Files\Unity\Editor\Unity.exe
This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information."
????????????????

Data Execution Prevention (DEP) on Windows Vista and above. This does not occur on every machine, but some users have reported DEP can stop Unity from working. To add an exception follow this guideline : http://windows.microsoft.com/en-US/windows-vista/Change-Data-Execution-Prevention-settings, "To turn off DEP for an individual program". Note: It is reported (but not confirmed) that Oct '11 security updates to Windows change the DEP setting to highest and this can stop Unity in it's tracks. Change back to the settings mentioned earlier.
