I tried installing the PTS client the usual way a couple days ago, but apparently the 124GB I have available on my SSD are not enough, since my drive was filled to the brink before the download finished. I tried following the guides I found online for installing PTS on a separate drive, but it doesn't work, because as someone who bought ESO on Steam I cannot just download the launcher from the ESO account page (even though I'm one of those lucky people who bought the game on Steam so long ago that I can still log in via the ESO account when there are issues with Steam).
So hence the question: how can I install PTS on a separate drive as a Steam user?
