Application Publishing

I am trying to create an Application and publish said application (in this case AccPac) to physical desktops, but without having to define a full View Desktop (IE linked clone) with the AccPac client software installed.  We are currently running Horizon View 5.2.0 build-987719.  To test the setup, I am using a definition of Adobe Reader X that we have defined in our environment.

While I can add my system as a member of a physical pool, when I attempt to assign one of the applications we have setup in our environment (in this case Adobe Reader X) for testing, I get the following Error:

Application assignment is not supported for Terminal Services or Physical Pools

Any suggestions or am I not doing something right here?

Thanks in advance...
