Hi everybody! I need your help 
I’m trying the new 4.18 version but I can’t create a c++ project, or add c++ class in blueprint version…
Everything worked fine with the 4.14.
I installed the vs2017 as I thought it will fix it, but I have the same error…
An error occurred while trying to generate project files.

Does anyone knows how I can fix it??
