RuntimeException Issue

Right now I’m installing grav on our local server here at work. We just updated our PHP version to 5.4 and now we are running into this issue (attached picture). I’m new to grav and not sure what this issue is caused by, anyone that can help would be much appreciated! Screen Shot 2015-05-19 at 2

Seems as though Grav does not have permissions to write folders/files

Yeah that was it! Thank you, that fixed the issue!
