Going back to this question. Is this trusted question going to pop up after the security alert pop up window (can't remember how it is for other s/W)? I have the UAC activated. Is it therefore I don't get this trusted questions?
The trust question you posted the screenshot, is to ask permission to run the INSTALLER (Windows still doesn't know anything about what it contains) only.
THEN, after you completed the installation, you should get other two trusting questions, one to ask permission to run the Addon Manager, another to aks permission to run the Couatl engine.
In any case, you said Couatl IS runnig, it's pointless discussing about trust issues, because if it wasn't trusted, it wouldn't have launched at all, not running without doing anything, like it seems to do now. And, the Addon Manager is running too, because the Coautl log shows it has connected to it.
So, your issue doesn't have anything to do with trust problems or UAC or so, it's just strange Couatl is running and doing nothing...
You need to wait a bit, because we have a special diagnostic version that I can send you. I'll send you a Private Message when it's ready.
