I use the Presenter with Windows 7 64 bit and had no trouble setting it. Connect the receiver, can install driver and off you go. As presentation software I use PowerPoint 2007 and Acrobat Reader for PDFs. For both programs the Presenter is suitable.
I would also like to emphasize that it is a radio link between sender and receiver. As a result, no "line of sight" is required and you can move freely around the room during the presentation as well.
One criticism is the positioning of the laser pointer button for me. It happened to me a few times that I have pressed one of the arrow keys while pressing the laser pointer. Maybe this is also due to my back Grundvervosität.
For those who may seek a presenter with the essential features and an integrated laser pointer, I recommend this device without a doubt.
