Resolving ActiveSync Errors
When a device is connected to a PC via ActiveSync, the device may sometimes show the error message "To synchronize this device, you must install ActiveSync 4.5 or newer on your desktop computer." This could be caused by a timing issue that occurs when switching from a USB serial to an RNDIS connection, and can be alleviated by configuring DelayConnectvalue of the HKEY_CURRENT_USER\Software\Microsoft\RAPIregistry key. DelayConnectshould not be modified unless the device experiences this error message.
