Front Panel Dilemma

[sumitrishi]

I am using Run VI invoke node to run a VI that is reentrant and for
passing a single paramter to the same I am using set control node. Now
the calling VI will be an exe when packaged and needs to run as an NT
service wherein I am not allowed to use any UIs. The set control would
not work otherwise is what I presume -I mean without a front panel
being loaded for the called VI. Please assist in finding a work around
or correcting me if I am wrong in my assumption.
