Rename eso64.exe to eso.exe
That should work until the next update, because you will get a new exe.
Give it a try, if it doesn't work give the files the old name to revert the change.
How about this: I've never been able to use the 64 bit client, as it's always the "wrong version" so likely never got updated. Is the only way to update it by doing so from the Launcher?
