Hi everyone!
I've bought and downloaded the game, but whenever I try to launch it a small error screen pops up saying that the game can't launch because it's broken. What do I do?

Same for me here on Mac. I've tried downloading the backup installers + installing via GOG Galaxy and both fail.

In case this helps anyone else - I followed the steps under support area for Grim Fandango under the second FAQs heading (sorry, I'm not allowed to post links), then opened the app by holding Ctrl and right-clicking, then hitting Open and it worked.
