My children play jumpstart, But it doesnt work as it says I need to install unity player- which I have it just doesnt run the game, downloads fine. I have windows 7 and it doesnt seem compatible- have done compatiblity troubleshooter and still nothing, Have cleared cache also.
If you’re using IE9, make sure you enable UnityWebPlayer Control in the Add on manager (Alt-X) → Manage Add-ons.
