Download and install RevoUninstaller (http://www.revouninstaller.com/start_freeware_download.html)and do the advanced uninstall.  This will use the problem programs built-in uninstaller and if that fail or leaves stuff behind, it removes registry entries and files related to that program in one easy to use wizard....

I downloaded the Free Trial version and ran the Uninstall and didn't succeed. The funny thing is that when I want to install a new software , I get the exact same error message

Are you running an AirCard, or some kind of 3G wireless?
You may need to update or repair the MS Installer.
