Failure to launch

It's most probably a problem with your graphics card drivers or specifically their OpenGL counterpart. Do a clean reinstallation of the latest graphics card drivers from the manufacturer website. Check the Graphics Card Troubleshooting Guide for help on how to do this. If this happens on Amnesia as well then it's best if you attach it's HPL.log as it's more useful compared to the Penumbra ones.
