I have bought Rayman 3 hoodlum havoc for the new year to play at an old game but it is impossible to launch. I have tried to reinstall it a lot of times. I click on the play button it becomes grey like if it launch the game but after some seconds nothing happens and it appears green like if i didn't click on it. Does someone have the same problem ?

I played through the game just recently without any issues. You can check if there's some sort of a setup in the game directory. I don't know though, because as I said, the game ran fine for me.

Also you can try running as an administrator or running without galaxy, launching the game exe straight from the game directory. Or maybe set some compatibility with an older OS.

I have same problem as guy at the top I think

Aha, got it working, using tips from second guy in thread
