Hey!

There usually won't be any activation keys involved as the game automatically links to your Ubisoft account.

If you do need your key however, you may be able to find one using this support article: https://support.ubisoft.com/en-GB/fa...-Key-in-Steam/


Should the issue remain, I have some steps for you to try -


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:

- Open Steam
- Right-click the affected game in your Steam library and select Properties from the drop-down
- Select the Local files tab and click the Verify integrity of game cache... button
- Steam will verify the game's files. This process may take several minutes
- Once the process is completed, the Check Window will automatically exit


I hope that helps!
