|What do you mean enable flash player? First off, I'm going to assume you mean Adobe Flash Player. Have you just tried reinstalling the program?|
Are you trying to play this game in a browser? If you are using chrome, you may need to disable the chrome built-in flash player:
Make sure that the game isn't asking for Shockwave Player as this is a completely different thing:
There is no reason for you to have to 'enable' flash player. Just make sure that you click OK to any Windows UAC/security alerts when you run the game, and that you actually ran the installer when you downloaded it (if you didn't, it should be in C > Users > username > Downloads, called install_flashplayer...exe).
