Greetings Gamer
Thank you for contacting The Elder Scrolls Online Team. We apologize you are experiencing issues with the game re-downloading. Listed below are some steps you can try to fix the problem:
First, players should make sure to disabling their anti-virus and firewall software as this may be causing a problem with the installation. Be sure to turn everything back on afterwards.
Next, players should run the installer/patcher as an administrator. This generally fixes any write protection or restriction issues that can sometimes cause problems.
Additionally, if players have overclock turned on, they should try to turn it off.
If this doesn't resolve the issue, pause the download and click on the Repair option within the patcher itself. If the Repair option is not visible, manually cancel the update. This should allow the Repair button to appear. If the launcher continues to update, click Settings and turn automatic updates off.
If players are still not able to get past that error message, they will need to uninstall the game completely, and restart the computer. Once this is done, delete hidden folders. To reveal hidden folders, please follow the instructions on the Microsoft website.
Now, open Windows Explorer and type C:\programdata in the address bar. Finally, find and delete the Zenimax Online or ESO folder. Then, re-download the installer from https://account.elderscrollsonline.com.
Players can also try repeating the above process and change the installation directory directly to the C: drive, outside of the Program Files folder.
If this doesn't resolve the issue, please reply with a copy of your DxDiag and MSInfo. Players can use this article if they require assistance with retrieving their DxDiag and MSInfo.
Thank you for your continued interest and support!
