Launcher can't install engine

Thanks for the replies, the problem kinda fixed itself. I re-downloaded the launcher installer and re-installed using the newly downloaded one and now it all works fine. Don’t know what was wrong before but if it helps for future reference, here’s the log. https://dl.dropboxusercontent.com/u/20531141/UnrealEngineLauncher-backup-2014.06.23-13.00.15.log

Thanks again
