The broadband kit modem's drivers were released for versions up to the Windows XP operating system. Since there is nowhere mentioned about Windows 7, you can try to install it using the manual way. After you plug in the USB stick, navigate to its drive using My Computer and manually install the application using the Administrator mode.
Once the installation finished, go to Device Manager (Star > Control Panel > System) and right click the yellow sign entry and choose Update Driver. Point the installer window to the folder where the program and driver were installed and follow the on-screen instruction.
