Applicable Products and Categories of This Article

I get a message "Twotrack.vxd" missing on the PCG-C1.

1. The driver for the Trackpoint has to be reinstalled.
2. "Start|Settings|Control Panel|System|Device Manager".
3. Expand the Mouse branch. It should say "Sony Stick-type Pointing Device". If this is not the case, double-click the device under mouse and select the driver tab in the window that opens. "Upgrade Driver|Next|". Choose "Display a list of all the drivers in a specific location|Next". Choose "Sony Stick-type Pointing Device" and click "Next".
