"the feature you are trying to use is on a network ressource that is not available."
Thats what I get every time I right click some , or left click the firewall icon.
I use symantec client firewall.
and when I cancel one of the install messages , they pop up again 2 or 3 times.
And last , when I left click a starcraft bot (stealthbot) , something called quicktime play tracks starts the same install like thing.
