I'll check it today.

Nothing, Windows can't find the register application and ask user what 
to do. The same behavior as when extension is not registered.

I can't agree here. What if there are few versions of VStudio installed? 
I've VStudio 4 and VStudio 5 working together. Unregister on 
installation/uninstallation it is not right. Look to app like VLC 
player, email clients, Notepad++ etc.
