First of all, please ensure that BE is properly installed for your game. You can manually install it by following the instructions on the download page. If that doesn’t help there might be a problem with your file permissions. To fix this please go to “C:\Users\[username]\AppData\Local\[game name]” (make sure that you can see hidden files/folders if you can’t find this directory) and delete the BattlEye folder there. If the issue still persists your system’s root certificates might be broken/corrupted. To fix them download and install the following update from Microsoft: https://support.microsoft.com/es-es/help/2813430/an-update-is-available-that-enables-administrators-to-update-trusted-a.
