Initially I wrote that the Desktop Manager needs to be installed for the tools to work. A user informed me that the Device Manager is enough as well. It does not even need to be running.
And I have another info about BbScreenStream. The LED that indicates when a capture is done was only thought as a gimmick. But now I found that it helps during presentations to avoid the problem that the BlackBerry misses a click of the wheel. Just only watch the PC screen and only click when the blue LED is off.
