Doing the ini edit, there is one thing you need to be aware of about nested folders.
If you have a .uproject located at: E:/MyUEStuff/Project/Project1/project1.uproject
The launcher will not recognize it. You need to have the location set to:
E:/MyUEStuff/Project1/project1.uproject
Or, you need to add (to the game.ini as above):
CreatedProjectPaths=E:/MyUEStuff/Project
It is only parsing 1 folder deep, not all of the folders. I hope this makes sense. Sleep is beckoning.
