Hello so I got For Honor on steam like 1 and a half a year ago but I decided to play it just now. I downloaded it and when I launched it, it wanted activation key even tho I own it on steam. I don't know what to do cause I got no key for ubisoft.

Hello there Pjedrix! Welcome to the forums

To correct this situation, I would like to suggest that you try the following steps:

Please, navigate to the Ubisoft Game Launcher cache folder, by default located here:
C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\cache

Open the cache folder and move the "ownership" folder to a safe location. Once you have backed up that folder, delete the "cache" folder. After deleting the cache folder, please verify the game files within Steam. If an issue is found, you will be given the option to Repair, click Repair. After repairing the issue, please verify the game again until no issues are found. When this has been completed, try launching the game again.

If the issue persists after trying these steps, please don't hesitate to update this thread. Thanks!
