Hi.
I noticed with the launcher if you have a project open and you want to update an engine version then it states you cannot do so you must close all open engines.
I was working in 4.7 and wanted to update to 4.8
I had to close my project, start the update and then reopen my project so that it can download in the background.
Nothing serious… just thought i would mention it as something you guys can maybe look into for the future.
