Microsoft Visual Studio 2010 Express for Windows Phone Zune

Not sure, if this is the place where I can post this particular question. I have been receiving error messages when I try to perform an action on my HTC phone, which is connected to my Windows Vista machine.
Here is the simple process that I use. I connect it using the USB cable and am trying to transfer an application onto my HTC phone. Unfortunately I am not able to do so, since it pop’s up with an error message.
Is this incompatible?
