Hi. Thanks for the reply and confirmation date.
But then why is there a Lumen folder (5x feature) in my UE4.27.2 install?
- Was “Lumen” always in UE4.27.2 installs?
- Can someone SS the Binaries DIR of their virgin UE4.27.2 installs?
- My concern is that Lumen (when in UE5x) makes my computer slow. So I absolutely want it off in any 4x project I’m working on. But now I see this folder in my 4x install (and other things I don’t use thus don’t want space wasted on, yet were modified today).
For clarification:
- I was not installing 5x nor had any downloads qued. (My 5.4.1 was installed a month ago.)
- I merely wanted to use the Epic Launcher to start the UE4.27.2 Editor, to make a new project (because I couldn’t find the shortcut directly to the UE4x Editor.) Thus I clicked the dropdown button to set my default editor from UE5.4.1, back to UE4.27.2.
- And all the engine versions are installed on an External drive, not on the Win11 OS HD.
Edit: you said “5.4.2 update” but I thought the latest was UE5.4.1. So did you make a typo, or is 5.4.2 on the way? 
- But I did click the Downloads tab (during the forced update), and it said it was downloading “UNREAL ENGINE 4.27.2.”
