[AccessD] Ribbons

Hey All
I put this in the OnOpen of my Main form and sent it to a friend to test 
(as I don't have Access2007).  It didn't work the ribbon still appears, 
is there something else I need to turn off???

If SysCmd(acSysCmdAccessVer) >= 12 Then
	DoCmd.ShowToolbar "Ribbon", acToolbarNo
endif

Thanks
