I cannot open any new projects.

So I just downloaded UE4. I open the engine, and select my template, and hit ‘Create Project’. But every time i do, this message shows up. No matter what I do.

If the picture doesn’t work, the message says ‘Failed to write output file “/Users/G.PDocuments/Unreal Projects/MyProject/Config/DefaultEngine.ini”. Perhaps the file is Read-Only?’. Can anyone help me?
