Consult the game’s forum or contact the game’s support

If you’re still seeing the Denuvo error, you might want to try your luck on the forum of the game you’re having problem with, or simply reach out to the game support. It might be a common issue or one that has already been fixed.

Run the game as an administrator

Running your game with administrator privileges can help avoid issues with game files not having enough permission to run properly. To try this, right-click on the game’s shortcut and select “Run as administrator”. This can help bypass certain restrictions and might solve the error.

Getting your games from reputable sources ensures you won’t run into unnecessary problems and supports the people who made the game.
