Select a bar file, a confirmation dialog will appear.

Click OK to confirm. A password dialog will appear. Just ignore the user field. This is the PlayBook standard login dialog, and I haven’t explored yet how to disable the username field. And you need to press the OK button (the “Return” key doesn’t work yet).

And this dialog should appear if everything is fine. After you fill in the password, it will start the installation. If everything is fine, then this dialog should appear.
