When launching a Unreal Engine 4 project from the Epic Games Launcher, the launcher closes and automatically reopens when an Unreal Engine 4 project gets closed.
Is there a way to disable this behavior?
If not, I would request this as a feature in the settings.
Thank you very much
seconded, did you find any answer yet?
This really gets in the way when you need to work with several projects open.
Its also counter intuitive when you want to use the store while waiting for your project to load. I had my position in the marketplace reset acouple of times because I keep forgetting about this. Really needs to be an option for keeping it open when you launch UE4, games Im not so fussed about it closing for.
No I didn’t find a solution yet. Good points tho. Its most annoying when working with more than one open project and browsing through marketplace/learningtab or library. And every time it reopens, it has to reload the library or marketplace which takes about 5seconds on my end. Also the backslash does not work as intended. They should build the launcher like a website where you can go back and forward. The steam client is a good example of how a launcher should work (imo)
Yes, it is very annoying. I wish it would just stay open unless I choose to close it. It never used to behave like this… maybe it is a bug and should be reported.
This is definitely annoying and probably not a bug but rather a feature (at least somebody thought it would be a good idea). As already pointed out, this makes it very difficult to work with several projects or work on a project in which you find yourself often closing and opening the project.
Could we please get a tick box to opt out of this new feature?
I agree, this gets really annoying. Epic, please fix this!
there is probably a workaround solution but I have to investigate it further. sometimes when I open and close a couple of projects, the launcher stays open. so there seams to be a bug in that not so nice feature but I can’t reproduce it right now.
To be fair “Minimize To System Tray” is a feature on its own and should have nothing to do with Unreal Engine. The launcher is also used by none-ue4 users who may want the launcher to just minimize to the system tray and not completely shut when closed, the feature makes sense.
Here the issue is that opening a project causes the launcher to minimize on its own for no reason. What if I want the launcher to use the “Minimize To System Tray” feature normally but just don’t want it to minimize on its own when launching a project?
I don’t think this is the answer, to be honest. In my opinion, there should be an option within Unreal to prevent this.
Hm… It seems the “Minimize To System Tray” checkbox in settings causes this behavior. I also noticed it doesn’t minimize to system tray when minimize window button pressed. Seems like the issue is bad naming of the feature and it confuses people. If someone can confirm my findings, I will then convert this comment to an answer 
Yes, conventional understanding of “Minimize To System Tray” is minimizing it to system tray when pressing minimize window button, but launcher doesn’t do that (it would be a nice feature to have), instead it minimizes to system tray when it launches an application, thus I think the naming is the problem. Name like “Hide To System Tray On Application Start” would be less confusing.
After reading your comment I got impression that your launcher minimizes to a system tray when minimize button pressed, it that true? For some reason it doesn’t work for me.
In my Opinion it answers this particular question because it stops launcher’s from Opening/Closing on engine start. And the right behavior for that feature name isn’t there on the first place (need to confirm)
I may be getting this wrong but my understanding of the “minimize to system tray” feature is that it does so only when clicking on the close button of the window, at least that has been my experience with all the applications that use this feature.
As a matter of fact no, it only minimizes when closing the window. That was the reason why I said that the feature is named correctly and that I believe this isn’t the solution.
Exactly what I was thinking. It would make sense to just add an option in UE4 to disable this.
I see, I stand corrected. It should minimize on close button and it does. Seems like they implemented feature and added on top another one.
I can confirm that the “Minimize To System Tray” checkbox in settings causes this behavior. Thanks for investigating
That’s exactly it.
So the option actually fixes the behavior the initial question was referring to, but it also makes the application actually shut down when you press the X button in the top-right.
It works well for me, since that’s the behaviour I want when I try to shut down the application, but I would rather the two features be independent.
As the comment above me mentions the option is responsible. As others have pointed out the UX writing is misleading. Naming it “Automatically minimize” should suffice or as someone else pointed out “Hide To System Tray On Application Start” would be better too. Just reiterating here.
For me I tbh just want to use 4.27 without the Launcher.
Tried solutions but nothing worked.
Idk why They make it like this.
