Payware airports and VDGS systems

Hello. I have a number of payware airports installed that boast working VDGS at stands. I am also aware of at least 3 software plug ins that need to be used to activate the VDGS functions - Nool, GSX and Aerosoft. However, the only airport which seems to have working VDGS is EHAM by flytampa. So my questions are…have I missed something in the install process and is there actual conflict with the three plug ins? Is there one plug in that runs with all VDGS armed airports?

Personally I use GSX but VDGS needs to be configured in an airport profile.

If an airport supports Nool or Aerosoft VDGS it usually includes installation file for the plugin.

EGSS for example has configuration window in iniManager where you can enable Nool VDGS, install the plugin or disable it and install GSX profile.
