Windows 7: 3 mobile broadband dongle works then stops

26 Jan 2010   #11

Windows 7

Windows 7 will allow you to install the 3 dongle software, so after you have installed the software right click on the desktop icon>properties>compatibility>run as Vista service pack 2>tick the box that says run as administrator.
