Since updating through the launcher is not working, the next step you can try is restarting the ESO Launcher followed by running a repair. If the repair gets stuck at 0%, you may need to download a new patch manifest file. Instructions on how to do so can be found below.
What do I do if I get Error 210 "PatchManifestError_DownloadFail" when trying to download The Elder Scrolls Online on Windows?
