Why do i keep getting this message: Error launching unity player

Every time I try to play f1 online the game I keeping getting the message error launching unity player. I have uninstalled and reinstalled and still does not work

Please try reinstalling the WebPlayer using the download steps below:

  1. Uninstall the WebPlayer via control panel → Add/Remove programs
  2. Restart your machine
  3. Open the link: http://webplayer.unity3d.com/download_webplayer-3.x/UnityWebPlayerFull.exe
  4. Install the WebPlayer
  5. Restart browser

This is not a fix. I have done this but when the web page is left unattended too long this error pops up.
The “reinstall web player” advice is not practical for real world applications.
