Hi there, I purchased a new laptop which has windows 7 and I have the huawei e220 vodafone modem. This works perfectly on other laptop. When I went through the installation process everything went fine - no problems. However when I try to launch it it says that no device can be found. Are they not compatible? It looks like it is installed on the desktop, in programs, c drive everywhere. Any help would be really appreciated. Thanks, Aisling

Here is a link to a tutorial on the subject. It seems convoluted on how to make it work. Also have you tried installing the software in Vista compatibility mode? http://www.7tutorials.com/make-vodafone-mobile-connect-huawei-modems-work-windows-7

To summarize, you need to do the following: Do all the installations from a computer with Windows XP installed. I tried to do this from Windows 7 directly and it did not work. Chances are it won't work from Windows Vista either; Install first the E220 Firmware from the archive you downloaded; Next, install the E220 Dashboard.
