Repeating update

[1Ruinmaster1]

I tried to backup and copy Warframe (steam-version)for one of my friends but when I tried the first time it started a 13GB "update" . When it finished I tried it again but then it started another 13GB update again! It also means I can't play the game before the update is finished. Why is this happening ,it's very frustrating?

Just download and install the game normally.

You can't do such thing with games that use their own launcher on steam.

Just erase / uninstall everything and install it properly.
