The file cannot be overwritten because a background application that automatically launches Configo when you connect your Prestigo is still running. * Philips recommends you to use the 'automatic updates' of Configo. Make sure this feature is enabled in the Preferences window of Configo. * Alternatively, open 'Activity Monitor', select the Configo process and click 'Quit.' Then try overwriting the earlier version of Configo again. If all the solutions provided above do not solve the problem, please chat with us (at the upper right corner), call consumer support, or contact your retailer.
