Packaging for windows

Hello friends!
I have Unreal installed on two machines, and both have the same symptoms:

Packages normally for Windows, but when I trigger the .exe to open the game, nothing happens, lock the hourglass and does not open.
Use the Win 7 64 updated, gtx 570 directx 11 8gb ram and have microsoft windows c ++ 2015 installed.
Can decipher this problem?

Try disabling the Antivirus Software for when you run it. Has solved the problem for me a few times.

It worked ! Thank you friend.
