The Microsoft has positively made the compatibility mode powerful in Windows 7. I might merely get basic utilize from my Zen Xtra in Vista, using Real Media Player to play tracks from the Zen Xtra, additional than in Windows 7 it runs perfectly. Fundamentally the driver for the Zen Xtra is mismatched by means of Windows 7. On the other hand, if you download the XP driver and right hit it off the installation file and select the Troubleshoot Compatibility heading and utilize the suggested settings to install the driver, then install the innovative Mediascource 5 for Vista, then the plugin for the Zen Xtra for Mediascource (together install without compatibility mode), you determine to get a warning that the driver is mismatched but ignore this and restart the system. I then started Mediascource software, noticed the Zen Xtra scheduled, clicked on 'Playlist', and it loaded, no tribulations! Playback, no tribulations, transfers to player, no tribulations. I am not using the 'Play 4 Sure' firmware update moreover.
