ReShade and Paralells

Hi! I have a friend that is trying to download ReShade on her Mac, using the Windows programme, Parallels. The ReShade is in the right folders, and her system meets the openGL requirement, but it still isn't coming up when she boots up the game it's attached to. Just wondering if there's any extra steps that need to be taken to make it work on Parallels or if it's something else?
