Installed OK but it keeps asking to download Flash Player

I have just installed Flash Media Server developer version 4.5 on my server, the Start Screen appears and keeps asking me to install Flash Player version 10.2 or above. I have repeatedly installed Flash Player 11 to no avail. I have tried to start the Admin Console but it just shows the 'get flash player' icon. I can confirm that Apache is running as I get an error from it when I try to access the Admin Console from the Internet. The Adobe web-site confirms that Flash Player 11 is installed and working correctly for the Operating System, Windows 2k8-R2. I have restarted the server to make sure everything has installed correctly, but it makes no difference. Any help or suggestions would be greatly appreciated.

Regards Ken.
