Hello,

I’m new in the world of Unreal Engine 5. When i build the third person map everything is fine but when i build my own project i can’t run the .exe. When i’m building i have no red error. The only yellow one is :

LogPackageName: Warning: DoesPackageExist called on PackageName that will always return false. Reason: Input ‘’ was empty

Any idea why i can’t run my .exe ?

Thanks guys <3

Hello Fayouss, Welcome to the Forums.

Yellow warnings should not interfere with your ability to launch your .exe

It sounds like your packaging is completing (You’ll see “SUCCESS” in the logs)

What happens when you try to run the .exe? Are you an admin on your PC? (As opposed to being on a school or work PC that might restrict running .exes) Have you tried right-clicking on the .exe and running it as an admin?

Hey man, just nothing when i click on the .exe and i already tried to open up in admin. When i run in admin in the win64 folder i have this message :

Thanks.

I did a google search for “unreal engine icu data directory not discovered” and found this thread with some suggestions.
