Hi... this error is not specific to Windows maps... I receive error code 8103010d when attempting to update the Nokia Weather Channel app. Unfortunately, it just hangs there... from what I can tell it downloads but it is unable to install. I have lumia 920.
Count me in as having this problem. However, there's no way I can see to uninstall Nokia Maps. Holding down on the app list, "uninstall" is grayed out for me.
