invalid installation package
 

Hi

I have made an app for the N9 in Qt creator, it works great when i run it on the device from Qt, but whenever I try to install the package I get an error saying "Can't install. Invalid installation package".

Can anyone tell me what's wrong with the package, or how I can find out what's wrong with it ?

The package can be downloaded here : https://openrepos.net/content/kif/osmapper.

I have other projects where the installation package works fine, so it should not be the Qt envoriment thats at fault.
