    He is my brother, and yes he has tried that so annoying because we want to play it together (I have a MAC and it's working fine) but his laptop just doesn't want it to work, weird considering his laptop runs games better than mine :/

  • ThreeEyedCrow
    After the latest patch I now have this exact problem.

    Reinstalling the entire game did not solve the issue. :(

    Same here. Have been playing fine since early access, now getting these errors every time I click play and the game tries to launch.

    Edit: apparently something went screwy with the patch files when i updated. Did a repair from the launcher again and it stopped.

    Hi guys!

    As @Loxy37 stated, please also run the Launcher as Administrator:
    • Close any running application;
    • Close the Launcher if opened;
    • Right click on the Launcher ESO;
    • Properties;
    • Compatibility tab;
    • Check "Run as administrator";
    • Click OK;
    • Then re-run the Launcher and process with the repairing.

    Using the Repair option on the launcher should resolve this issue.
    You can do so by following the steps below:
    • First, start The Elder Scrolls Online launcher by right clicking on the icon on the desktop and selecting "Run as Administrator".
    • Wait for the launcher to finish starting.
    • If multiple ESO clients are installed and available through the launcher, make sure to have the correct version highlighted by clicking on it once.
    • In the middle of the launcher there will be an entry for Game Options next to an icon of a small cog wheel.
    • Open the Game Options dropdown menu and click on the option for Repair.
    • Allow the launcher to examine all the files for the game. This may take some time.
    If any files are found to have problems, the launcher will re-download those files.

    If you are are still receiving the same error message after following these steps, please contact our Customer Support for further assistance.

    Thank you for your patience.
