sorry, this was a bug introduced in the 29 release, which has been fixed for 30. In the meantime you can add app server manually. Go to advanced, devices. Select each PC device from the tree in the left one at a time: "CORE", "Core/hybrid" (a child of CORE if you have a hybrid), and each M/D. for each device click the link create child, then click the button to pick the device template, select the category "App Server", and add an app server device. when you're done, reboot. Then he will be able to rip, lAunch applications, browse Web, and all the other stuff you need an app server device to do--its role is launching external applications, and without the device the system cannot do it.
