Problem is, I can't install it. It says the aouthor is locked and there's just no way to unlock it. Tried Administrator mode, and even Apploc. What else shall I do?
You have inadvertently Un-trusted us as a Publisher (even a while ago), so nothing signed by us will run. This can't happen automatically, only you can do this.
To fix 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)
