shortcut broken on AIR application update

When I push out an update for one of my desktop AIR apps that a client may have installed on a Windows 7 or 8 machine, the shortcuts to the app become broken and therefore useless. This gives my clients the appearance that my application is busted when it is not. I continuously have to instruct Windows 7 and 8 users to delete any shortcuts and go to the install directory and create a new shortcut.

Note that I use the Apache Flex 4.13 build AND that I only tally the version number in the *-app.xml file as I always have.

Thanks,

Jack Ring
