Build 767 doesn´t start

Hi there,
i can´t start the 64 bit build 767, launcher works, but clicking on "Single race" shows the blue rfactor2 start screen for a few seconds, but then a popup with the content "rfactor2 doesn´t work no longer" appears.

My Specs:
MSI X79-GD45MA - Intel Core i7-3820 - 16 GB CORSAIR DDR3
GTX670 - SAMSUNG SSD - LG BluRay - Windows 8.1 64 Bit Pro

 

Is this a brand new install from fresh?

 

Yes, new and fresh...

 

UI related? There is another post that say the UI is not found, with no UI, game will not launch.
I didnt had that problem since I installed my own UI and HUD from begining.

 

Just installed the Mini UI, the same, game doesn´t start at all.

 

install some content !

a track and a car, You should be good

 

Did multiplayer work?
How's 32bit single and multiplayer?
Any other content installed besides Mini UI?

 

Just installed ISI´s Megane Trophy and LimeRock Park, what can i say, it works!
Thanks a lot for helping out...

 

same thing here - you need to have at least 1 track and 1 car installed

 

The bug requiring to have a track and a car installed is solved in unstable 769.
