This means that it has been signed with a certificate made by the Mimer company themselves. The properly signed packages are available for their customers.Try this to install your package. This is something you most probably must do anyway to testinstall your own application.1. Goto to Tools -> Application Manager -> Options -> Settings.2. Inspect "Software installation". Set to "All".3. Inspect "Online certification check". Set to "Off".Be happy.
