Installing the game

I installed the game and now it shows that it is not installed. Which file should I specify so that the application understands that I have installed the game?

The folder does not recognize ,Only the file
Make sure to untick "Read-only" option from game folder properties. Then open the launcher with admin rights. Press "Set already installed game" and provide path to "Diablo IV.exe" file.
thank you very much. I was already thinking of reinstalling. But it worked
