I tried to install the driver software for the XBox 360 controller on Windows 7 64bit after formatting my computer (before this it worked flawless). But everytime i try to start it the following error occurs: "Couldn't run the application properly (0xc000007b)". I already tried reinstalling it and older versions of the driver (v1.1 and v1.2). Seems like Windows detects the controller without the driver as well, but i can't use all buttons (i.e. the analog stick).
