All you need to do is download the Microsoft Powertoys from the download area on this website. Go to the download area and search for Powertoys. You want version 2. After download you will see the file is named hpcv2pt.exe. Run it and it will install the PowerToys to your Microsoft Activesync folder which was created when you installed Activesync.
You don't have to sync however...just go to the folder and open the Powertoys folder, and in there you will find a ppaint folder. In that folder you will find the cab file titled pp_sh3.cab.
Copy it to your CF card and install it on your 680.
