(Windows 2000) The PDA Module installs Microsoft ActiveSync 4.2. You might receive a Microsoft Office Outlook error that states Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Office Outlook and set it as the default mail client. Workaround—You do not need to install Microsoft Outlook nor does Outlook have to be your default mail client. Click the OK button to continue installation. The PDA Module automatically installs ActiveSync 4.2 if ActiveSync is not already installed. When you install the PDA Module and do not already have ActiveSync, the installer automatically reboots the computer without alerting you. Workaround—Rerun the installer (setup.exe) to complete the installation or install ActiveSync before you install the PDA Module.
