I just spend an hour on finding a way to only install the driver but not the Wireless Manager Tool that comes with the package for the US Robotics Wireless USB-Stick Model 5423 on Windows. I needed to do this because for some reasons the Manager could connect to the router but Windows didn’t get the connection. This happened to me before and in case anybody has the same problem here’s ther workaround:
Download the driver from the US Robotics-homepage. You’ll get an .exe-file which installs the driver and the Wireless Manager. Now, here’s the trick: Open the .exe with 7zip or whatever unzipper you use. You’ll find a folder called Driver inside of the package, extract it and use it to install the driver manually through the Windows Device Manager. That’s that.
