After downloading, just double click on the file and it will automatically unzip to a folder you specify. Unzip files in a special folder called Rockwell for example. Then, right click on My Computer and select properties. Under device mananger, highlight Rockwell Modem under modems and click properties. Click update driver, and click Have Disk. Browse for the driver in the folder you saved the unzipped files too. Then OK, and OK. If no modem is in device mananger, use Add New Hardware under control panel and select install device myself and select modem. Then Have Disk and browse the same way. Good Luck!
