      Download Summary:

      You have not selected any file(s) to download.

        • Important: Please uninstall all prerelease versions of Sync Framework prior to installing this release version. This includes Sync Framework 2.0 CTP1 and Sync Framework 2.0 CTP2. Sync Framework 2.1 can be installed and will operate side-by-side with Sync Framework 1.0 and Sync Framework 2.0. Please ensure that you download and install the SDK appropriate for your system. For example, SyncSDK-v2.1-x86-ENU.msi includes the Sync Framework components for x86 machines.
        • It is not possible have full 32-bit Sync Framework 2.1 SDK installed side-by-side with the 64-bit SDK; therefore you will have to install one version of SDK (64-bit) completely and only selected components of other version (32-bit) of SDK. See Sync Framework Tips and Troubleshooting topic for details.

        • Make sure you have the latest service pack and critical updates for the version of Windows that you are running. To find recent security updates, visit Windows Update.
