Use these instructions to update your barrel scanner without it being docked. Make sure it has internet connectivity before proceeding:
On the device, go into Start -> Internet Explorer and navigate to the following address http://go.vintrace.net/legacyscanner.
Download PistolGripCab.cab if you are just updating or all of these if you are starting fresh:
The files are installed in the order presented above. Internet Explorer will prompt you to download the file with an option to “Open the file after download”. Make sure this option is checked, then click “Yes”. This will download the update, and launch the installer.
In the installer you will be asked if you want to remove the old version. Click “OK”. If it asks for an installation directory, select the “Device” option (which should be the default option). Click “Install” in the bottom left.
Run Start -> vintrace on the device, sign in, and check to make sure that the version number is the one you should now be using.
