Q: I connect with ActiveSync, but when I try to test my connection under Platform Manager in the development tools, I get the message, "CEMGRUI: Unable to connect to the device. Please make sure you have installed the underlying transport (e.g., ActiveSync) and have a device connected." What gives?
Make sure that you have installed and are using the SDK for CE 3.0. Also make sure you are using the current build of CE released for your product.
