Avast 2014 Firewall blocking WM Recorder 14

Does anyone know how I can add manuel exceptions???
I cannot find anything in this new version anymore. When I shut down the firewall the software is working without problem, so it is clearly blocked by Avast.
Can anyone help me please?

I have the same question - firewall is blocking Microsoft ClipArt - but I can’t figure out how to add the necessary path to the firewall exceptions - anyone know how to do this???
