Hi there! I have a Dell Axim X5, using Windows Mobile 2003. I have Windows 7 Ultimate x64. Before that, I was using Vista Ultimate x64, and had no problem connecting my Axim to my computer. Now, I am trying to make my Axim work with Windows 7. After much hassle, I successfully installed the drivers. The Axim now shows up in: My Computer, Devices and Printer, and the Device Manager, all without any problems, errors, or yellow exclamation points. All says the device is "working properly." However, when I open Sync Center, it does not see any device. Also, when I click on Windows Mobile Device Center, the application does not launch. The only thing that comes up is the Connection Settings screen, shown here: Neither Sync Center nor WMDC seem to connect. Although wmdcBase.exe is running according to the Task Manager. I have tried: uninstalling and reinstalling WMDC, updating via Windows Update, trying a new USB port, uninstalling and reinstalling the device drivers for the Dell Axim. Please, how do I fix this?? Thank you!!
