Can't run game after packaging!

Good day!

If I create any project and set project name as default “MyProject” I can package it and use it well. But if I will name a project any else name but “MyProject” (“BlaBlaProject” or “WhateverProject” for example) and package it - the exe file (“projectname”.exe) will open forever (endless loading with nothing happens)

Create FirstPerson example named “MyProject” - packaging and work
Create FirstPerson example named “WTFProject” - packaging, endless loading of exe file

Create FirstPerson example named “MyProject” - packaging and work
Create FirstPerson example named “WTFProject” - packaging, endless loading of exe file

Same for ThirdPerson/ Vehicle/ etc…

How could I fix it?

I have the same problem!
If you do not change the basic name when you create project, then after packaging it starts normally. But if you enter any other non-standard name, such as “TheProject”, then after packaging at startup .exe file the game will run indefinitely.
And my UE version is 4.10 too.

Hey! I found the problem!
If you have installed the AVAST antivirus, it will block your .exe because your program name has non-standard name.
Turn off the antivirus and get fun!

Thanks, mate! The problem is Avast antivirus.
