If you are having trouble downloading or installing The Elder Scrolls Online, you can try the following troubleshooting steps:
Check Service Alerts
Verify the servers are not undergoing scheduled maintenance here.
If the ESO server or platform is undergoing maintenance or experiencing an outage, you will not be able to connect and download the game client until it is resolved.
Power cycle and then test your network
Turn off your network's modem or router for 10 minutes before rebooting.
Add ESO as an exception to your antivirus software
Each antivirus program is different, and we recommend you view your antivirus developer's website for full instructions on how to add exceptions.
The application files that may require exceptions are:
Some antivirus programs require entire folders to be selected instead of a single file.When this is the case, the file paths below are what players should use. If required by the antivirus program, include all subfolders since every file is critical to run the game.

Give ESO and Steam access to Mac
If playing ESO on Mac, you should ensure that both Steam and ESO have access to your machine by navigating to the Security & Privacy menu, selecting Privacy, then clicking on Accessibility and adding them to the list.
Reset the ProgramData folder
If playing on PC, you can also try resetting the ProgramData folder:
Close both ESO and the ESO Launcher.
Open the game's installation directory.
Open the folder named Launcher.
Inside the "Launcher" folder, there is a folder named "ProgramData".
Rename the "ProgramData" folder to "ProgramDataBackup".
