Windows 7 Ribbon redist DLL for Vista and or XP ?

Question

Hello,

We need to install Win7 SDK to create a Win7 ribbon app. But can the ribbon app we create under win 7 run under Vista and XP ? Is there a RibbonCtrl.dll file that we can (freely) redistribute with our application ?
I remember ye old time, when Win95 added new common controls, Microsoft allowed us to redistribute the new control DLL commctrl.dll with our applications, so our app can run under windows 3.1 too !!
Thanks,
Pierre

Ribbon is available for Vista, not XP.  See
