i had the same problem... basically steam is a lazy ass and doesnt install the launcher folder so you have to ask some 1 to send it to u then add it to the eso folder in steam
also as a bonus if u get a timed out error close the game. the launcher and steam then run steam as admin
The driver update did not fix my issue. It said I had the same or newer already installed. I just bought a new ASUS ROG753 and can't get past the installer. So windows 10 and ESO installer if not compatible I think they need to fix it. I currently sub and have it on my old laptop. I was looking forward to playing it on a more powerful machine. I don't have this game on steam. I bought it directly. I have also pre purchased Marrow wind... I need this to work!
