Yes, they are Nokia apps. I am very excited for the Beamer app as it will allow me to give presentations from my phone. I have contacted Nokia Cares Us via twitter - they are aware and working on the problem.
I just got the Lumia Black update however I get a message that Nokia Beamer app is not available for my phone or carrier. All the other black specific apps are installable.
I suspect Verizon is blocking this one. They either want to charge us for it or are afraid of bandwidth issues. I really hate when VZ does crap like this.
Nokia Beamer is THE app I rally want. I do lots of demos and this the only way to project apps on my phone to a laptop.
@mhammo - This was not Verizon's fault. Nokia had problems with the software and needed to make changes. They have since reloaded the Nokia Beamer and Nokia Storyteller back in the Microsoft Store and it is available. I have downloaded both and they work great!
