Hello, I’m having issue since yesterday trying to reach Unreal Editor for the first time.
I think my computer hold the minimum specs and I can’t find any solution for now (after hours of search).
I can’t start EpicGameLauncher.exe unless I add -Opengl to the target launch in the exe properties.
Once it’s launched I’m able to download the last UE (4.12) but if I try to run it, pop-up show, run up to 18% then disapear…

I’ve already try to find any process associated with Unreal Editor on the task manager but there’s nothing (it only pop then hide if I try to launch editor)
I’ve already uninstall several times (including deleting any associate files)
My GPU drivers are up-to-date from manufacturer depot.
I’ve tried to manually launche editor from Epic Launch install dir, nothing pop.

Might the editor launch crash be caused by -Opengl option on EpicLauncher ?

Here’s my dxDiag file : DXDIAG

And the last log : LOG

And here’s one log after using -opengl : LOG-opengl
In this case, launcher does start (if launched as admin ofc) now I’ll try agin to download then launch editor (and pushing logs here)
