Hello, 

I purchased this game on my Mac but I can't open the app

The screen is the error message (in French)

Do you have any solution ?

Hello it seems like you have selected the exe version instead of the .app one, unless I am mistaken? For mac, please select the .app if the problem still persists and you cannot run the app at all, please email me redlady553@gmail.com for a refund, with proof of purchase, thank you!
