Optional: If you are installing to a Windows Mobile device, make sure it is connected to your computer and that ActiveSync (Windows XP) or Windows Mobile Device Center (Windows Vista or Windows 7) shows that it is connected.
Run the installer. Your browser may run it automatically, or it may save it to your Downloads.
When asked, choose whether to install the Windows PC version, Windows Mobile version, or both. The install will complete.
If you choose Windows Mobile, you will see additional prompts on your Windows Mobile device to finish the installation.
