Game not exporting correctly to windows

Hello, I have created a simple Endless runner game in unity and in the editor, everything works 100% but when I export it to windows, the high score/leaderboard function just doesn't work so its as if no one is scoring anything. I'm not sure if there are any bugs I cant see in unity but I exported it to my mac that I use unity on and it worked 100% but need it on Windows. Is there a way I can debug it while testing it on Windows to see if it's throwing up any errors or any things I can try to try and get it to work OK?? I have the same issue when exporting to android.

Thanks,

 

You can enable Script Debugging when building and see if there are any script errors.

Otherwise, you can enable remote debugging and use the Unity console to see what your scripts are logging.
