First off let me say I am really liking what you folks are doing with this hub! Just finished a prompted update to 0.13.0 and decided to add 2018.1.b8 - I only have the editor selected to install and I keep getting Editor Download failed. On a side note, I was testing the ability on the previous version to run two copies at the same time. A copy of 2017.3.1f1 - light baking a scene and just doing some standard scene building on 2018.1.b7 in the other. Separate projects. I had an issue where with the graphics card and my baked scene went all weird and I had to reboot. Took some fiddling after to get the lighting to settle down again so that has made me shy away from running two copies. I hope you can confirm there should not be any issues with running two copies of the editor at the same time?
