Well, seeing as many are still missing the picture of the toolbar, Patchou, consider forgetting what you said and move the toolbar between the radio buttons and the "Install" button.

This way, they have doiuble the chancde of seeing it, one when they click the radio button, and one when they click the install button.

You might also consider a timer on the install button:
Install (5), Install (4), Install (3), Install (2), Install (1), Install
