Well when I click on it windows help opens and says there is no such chapter, then i searched on the internet and found that this was related to win firewall, I then configured the firewalll to accept the setup but that didn't change anything.. Any idea?
No, it's not the firewall. A firewall will prevent a software to go online, but it will not prevent to run. What's happening here, is that you used the option to block everything signed from us, when you were presented with the choice.
To undo this, go to the Control Panel, under "Internet Options", look for the "Content" tab, there should be a "Publishers" button, that will list the software publishers that you trusted, and another tab with untrusted publishers. If you see "Virtuali s.a.s", remove it from both tabs (especially if it's under untrusted)
