Right now Unreal 4.4.3 will not run on my computer. It simply crashes upon launch. This just started happening shortly after the update to the Unreal Engine Launcher. Any ideas? Please help.
I can only confirm that i have experienced the same, but do not know the reason.
That’ s why i downloaded the new 4.5 preview.
4.5 launches as expected for me , but may still have some flaws in its beta stage.
I really appreciate this. I don’t feel as isolated now! 
This version works fine for me at work, so it must be some incompatibility with my machine at home. I may download the 4.5 soon.
Thanks for your communication!
Hi Drausch10,
Apologies for this one getting overlooked. We are going back through a lot of these posts now in order to resolve them.
Are you still experiencing this crash or did it get resolved for you in a newer release of the editor?
If it’s still an issue let me know and I can look into this further.
Thank you!
Tim
