Legal complicated installation, otherwise super

After I (computer ^^) the recessions read here on how to install here I thought it was to bring the small part with me to work for me no problem. Simply follow the procedures from here and then having the thing.
Unfortunately I was wrong.
As so often it does not work the way you want right away.
After I could not get up and running and the driver of the CD I first took a few weeks distance from the part until I found just the riddle.

The right approach:
In the device manager I have pressed the "Update Driver" with "Unknown Device" on.
Then I've only gone to the list of device drivers, then on "All Devices", the next location (C: \ Program Files \ Microsoft Xbox 360 Accessories \) specified and then select the inf file.
Then XBOX 360 Wireless Receiver selected and fertich.

It worked for me, maybe I could help so one or the other yet.
