Error 104 - DownloadError_NotEnoughSpace

KingOfDodos · March 2021

Hi everyone,

when i try to launch the game i get the Error 104 - DownloadError_NotEnoughSpace.
The launcher and the game are installed on a hard drive that has 491GB free, so i hope that it is enough space for the patch.
The other HD ( O.S. one ) has 37GB free, but there is nothing installed on it connected to ESO and i've never had issues with previous patches.

I've read that it could be a antivirus issue, but i tried to turn it off and the error is still present.

Thanks everyone for any hint.

Frequently, Error 104 is due to an anti-virus program blocking the patch. In some circumstances, the exception will need to be removed and re-added back as an exception to your antivirus program.

The application files that may require exceptions are:

Bethesda.net_launcher: C:\Program Files (x86)\ZenimaxOnline\Launcher
ESO.exe: C:\Program Files (x86)\ZenimaxOnline\The Elder Scrolls Online\game\client\eso.exe
ESO64.exe: C:\Program Files (x86)\Zenimax Online\The Elder Scrolls Online\game\client\eso64.exe
Steam.exe: C:\Program Files (x86)\Steam\steam.exe

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 anti-virus program, include all subfolders since every file is critical to run the game.

C:\Program Files (x86)\Zenimax Online\The Elder Scrolls Online\
C:\Program Files (x86)\Steam\
