Seems to be version: 378.49 GeForce Game Ready Drive, there are conflicts
Update will be unable to start the game

I did not get the error file
Just the game will not start, the card is loading
I roll back to the old version does not appear after the problem.

Why do you report this here? This has nothing to do with rftools. Latest nvidia driver doesn't work with modded Minecraft. Not an rftools thing

Haha, sorry. I also later learned that, because the driver problem.
