Internal Compiler Error

Unity will not compile a single script anymore. Even in a fresh project. Happened immediately after installing 4.2.2

    Internal compiler error. See the console log for more information. output was:Successfully compiled ‘22’ file(s) to ‘C:\Users\Brandon\Desktop\Drone Wars\DroneWars_Files\12-6-12\MediaFair\Temp\Assembly-UnityScript.dll’.

Would be my bet as well. Either AnitVirus software or file permission issues.

Are you sure you installed Unity with administrator privileges? Otherwise the installation might be corrupted due to missing files. Also make sure you execute Unity itself with admin privileges. I guess you are on windows?
