What should I do if my handheld scanner doesn't work or doesn't send barcodes to the internet?

First check that the barcode icon is visible in the lower right corner of the Windows clock. If the barcode icon is not visible, the BarTrack software has not been installed correctly. Uninstall (via startup, all programs) the BarTrack software and e.v.t. the USB Driver and reinstall the software. Make sure the USB cable is not connected during installation.
