Started Warframe on steam, then deleted it, then redownloaded it again but from the official Warframe website, not from steam. Now i wanna reconnect it back to steam, but it says i gotta redownload the game files, even though i already have all the game files up and running. How do i make it so that steam recognizes the already downloaded game files and links my warframe into my steam account?
You can link the steam install folder to the standalone files. I did this a couple of years ago and it worked fine, it’s a bit of a hassle though: https://warframe.fandom.com/wiki/User_blog:Rhionhi/How_to_set_up_warframe_to_switch_between_steam_and_stand-alone_clients_with_only_one_install_(For_tennogen_swag,_of_course)
If everything went right, after linking you can run the steam or standalone version at any time and they should only need to download the launcher.
From the sounds of it you don’t really need the standalone install anymore so you could probably just redownload the steam version and use the same login details you do on the standalone though, then delete the standalone when you’re confirmed the steam version is running OK.
