Hi, I'm having the same issue, however i get a slightly different error message. i have gone through pretty much the same steps, re-installing Leadwerks, running the vcredists.exe and the openAL one, i have also made sure all my drivers are up to date. it appears that my issue has to do with shaders and C++, as it seems to load up until this one file.
I am unable to enlarge the error popup to read what the rest of it says.
Thank you
