I have recently added two contents on OVI store and both being signed by Nokia for free, Thanks

I have observed a strange behaviour when I try to download these applications from OVI store. When I download any other app from OVI store, it automatically installs on my device and the 'Download' button turns to 'Launch' so that I can open the current installed application.

But when I downloaded my own apps(may it be game/theme), the app was not installed automatically, and the button turned into 'Open File'. When only I click that button, the application is installed on my device. But I am still not able to launch the application from store.

Is this the case all users will face when they try to download the apps signed by Nokia for free? If yes, it would certainly add confusion to users, as they are habitual to normal installation process.
