2.79 Crash on Render (Except Viewport) I just upgraded to 2.79, very excited about the new features (specially the Principled BSDF) but every time I press render image or render animation, it just closes. If I run blender from the command prompt, I can see the error 

RNA_pointer_get: SceneRenderLayer.cycles not found.
Error: EXCEPTION_ACCESS_VIOLATION    


Google turned up a couple dead threads, and nothing changed when I tried what was suggested.

I tried just making a new file, empty scene with just a camera, press render image and it closes. Same thing happens if I expand the preview pannel on a material. Strangely enough, viewport render still works.

PS: Is GPU support seriously gone? So far, 2.79 seems like a downgrade.
Using the "Repair" option with a fresh download of the installer from blender.org did the trick. Also fixed GPU rendering abilities
