The most common reason for the error message "Failed to Launch Game Client" is that your antivirus detects ArcheAge as a possible threat. To resolve this, you need to whitelist ArcheAge in your antivirus software. The exact way of doing this depends on what security software you're using, so your best bet is to check the software's website.

If you encounter the above error after a period of inactivity, please ensure that the game's Version.dat file reflects the correct version data. You will find instructions for how to do that on this page.

If you've successfully whitelisted ArcheAge, and if the version data is correct, but you're still receiving the above error message, please follow the instructions on this page to collect your Launcher logs and submit them to us by clicking the button below.
