FOS, FOS Track, and Flight Explorer can now all be ran on the same computer as long as the customer is on Flight Explorer version FE Professional Edition 15.X. Instances of FOS, FOS Track utility, & FE should be running on the same machine (virtually),MyFleet selection in FE should be set for Desktop Interface which will allow the fleet data to be pulled from FOS FOStrack should provide insight if the data from FE is coming into FOS.

Also Flight Explorer will only track flights by the tail number.

Below are screenshot that will confirm Flight Explorer and FOS are linked correctly.
