unity 3.1 for windows

i downloaded unity 2,6 first,and that was working perfectly but when i wanted to update it with unity 3,1 it gave me the error: the application can not start properly (0x000007b). Click OK to close the application, when i tried to open it is there anything to fix this with?

Send a message over to Unity and they might have a fix...

Also, try again later on when another beta version comes out...

Good luck!
