did anyone knew how to install active sync to windows 7 Ultimate RC?i have tried vista version and xp version too ....

I don't believe, and I could be wrong about this, that ActiveSync can be installed on Windows 7. I suggest posting to the Windows Mobile forum for further help...http://social.microsoft.com/Forums/en-US/windowsmobile/threads/...or use the Sync Center...http://windows.microsoft.com/en-US/windows-vista/Sync-Center-frequently-asked-questions...or Device Stage...http://windowsteamblog.com/blogs/windowsexperience/archive/2009/01/08/device-stage-a-new-way-of-interacting-with-devices-in-windows-7.aspxhttp://windows.microsoft.com/en-us/windows7/products/features/device-management MS-MVP Windows Desktop Experience, "When all else fails, read the instructions"

Hi, Windows Vista and Windows 7 use Windows Mobile Device Center to manage Mobile device instead of ActiveSync. You can download it here Here is a similar thread for your reference: http://social.microsoft.com/Forums/en-US/windowsmobileactivesync/thread/742ff7c5-4bf8-46ea-9010-bc18c22d1ea9 Hope it helpls.Vivian Xing - MSFT
