WampServer

I have turned off my firewall. I have stopped and started Apache but still no luck. Firefox wants to download the page instead of rendering the page. "You have chosen top open <blank> which is a: application/x-httpd-php from Test Port Check: Your port 80 is actually used by : Server: Apache/2.2.4 (Win 32) Pres Enter to exit... What do I need to check/change?
