Since there does not seem to be an official binary of the windows client sample for controlling the ARDrone. I decided to compile the sample project, which is available in the official sdk. Sadly the process of compiling the sample is not straight forward and requires a lot of tweaking [1, 2]. Nonetheless, I finally managed to compile a version, which is working on windows 7 x64 and is compatible with firmware update 1.5.1 of the ARDrone. It can be downloaded here:
ARDrone1.6Win32Client.exe working binary of ARDrone SDK 1.6 win32 client
You will also need to have an update to date version of the DirectX End-User Runtime [3].
