hello, i have the same issue with "please ensure steam is started" but my Rune is only .nfo file that means i cant rly open it and extract anything from it, and dont rly feel like downloading 2 whole days again, anyone can help me please?
Because you still not crack it before start game. After install, you must open .iso file, you will see "RUNE" folder, copy all files in that folder and paste to your game's dir, enjoy ;)
steam is open i added it as non steam game and its still didnt work
i opend it from steam/local and this message still pops
You can see tutorial here too (it same for almost games):
