MS Dynamics AX 2009 Set to Create Websit

I’m trying to create an Enterprise portal and Role center on a Windows/Sql 2008 r2 X64 server. When i try to create the website, i get a message box saying: “MS Dynamics Ax cannot create a site because Windows Sharepoin Services is not installed on this computer”. I have WSS 3.0 sp3 installed, IIS 7 with 6.0 compatibility. I applied the DAX 2009 SP1 update. Then I tried to update the AXPortal using this command “CD C:\Program Files\Microsoft Dynamics AX\50\Setup\ AxUpdatePortal -updatewebsites -iisreset -verbose” Finally it command also success. But still I have same issue help me out… Thanks
