ESO launcher re-downloads the entire game multiple times a year

I have a second PC at my parents' and ESO Launcher always re-downloads the entire game every time I launch it. I use OneDrive to sync AddOns but other than that there's nothing out of ordinary. Considering the internet speed is only 50 Mbps this is a huge issue for me.

Any suggestions are welcome. AI chatbots didn't help at all...

P.S.: Forum search is busted (AGAIN?!) so I cannot search for similar issues which I am sure are many already.

    1. Downlaoded fresh ESO Launcher Installation.
    2. Renamed the folder.
    3. Installed Launcher from scratch.
    4. Started game installation.
    5. Paused and exited.
    6. Copied files over from the older installation.
    7. Started new launcher.
    8. Re-downloading everything again.

    What browser do you use? I use Edge, a quick search using "eso game reinstalls every time I open launcher" gave me loads of results, including a fairly extensive AI response(Co-Pilot I believe).

    Got the links below from a forum search......

    Not sure if there is any helpful info in there for you.

    Edit:- because I'm an idiot..... I'm currently on my tablet so that search was done with Google not Edge!!

    The game is re-downloading EVRYTHING AGAIN. It's been like 2 months since I've been at this PC. This is the only game that does this.

    The launcher always shows the full game size when updating, but it's not actually re-downloading everything. I'm certain it's not because if it was it would take hours, like it did the first time I installed, and it doesn't. It's just bad design of the launcher UI.

    If you haven't played for months there's probably a bunch of data to install, but it still shouldn't take long. About how long does each update take for you? Is it over an hour?

    It appears I can't edit my post. I want to add: On a slower connection like yours it might take longer than mine, but my point remains: When you update, is it actually taking as long as I full install?

    Yes.

    Is the previous game install where the installer expects it to be? I've seen another post which implies that the installer doesn't actually check for alternate locations. Also, you mentioned using OneDrive to sync your add-ons: you may want to check that OneDrive hasn't helpfully moved all your game files to the cloud and just left a symlink in the folder's place (which the installer wouldn't recognize/follow).

    Yes, everything is in its place. I even tried repairing but it still downloaded the entire game.
