Launcher + Marketplace downloader for Linux

First of all, I would like thank you for making this. It will be a huge help to a lot of UE4 users. Btw I just had an issue: my Launch UE4 button is disabled. It basically didn’t even identify the version. Even tho I have it installed. Any idea why this happened? I tried changing the directory. To the folder where the Editor is and updated it. It didn’t work. Can you please help me out? I will greatly appreciate it.
