1. Go to: catalog.update.microsoft.com (it has to be opened with Microsoft Internet Explorer)
2. Search for "Xbox Wireless" which should give you 11 results
3. I've chosen the third one (version number 19.29.20.953) because it has the latest version number - click "add" on the right side (might be different wordin english)
4. Open that shopping cart thing in the top right
5. Download the driver to any folder and go there and unpack it using winzip/winrar
6. Plug in the wireless receiver and open the device manager
7. It should show the troublesome receiver as an unknown device called "XBOX ACC"
8. Right click the device, select update driver, select choose manually
9. Navigate to the folder where you unpacked the downloaded thingy
10. Install -> PROFIT
11. Controller and Wireless dongle should pair and work just fine!
