When I packaged Privileges 1.5.2 with Composer, I added a Postinstall-script that installs a privileges-helper.
I tried App Installers to update Privileges to 1.5.3; it installed fine, but then the helper was still in version 1.5.2 and therefor did not work.
Does anyone know a way to automatically install the latest helper after Privileges is updated via App Installers? you cannot add a postinstall-script to App Installers (yet?)
