Auto update problem in FC3 training?

[xylem]

When I go into the FC3 section of the 'Training' menu, each plane I select gives an indication in the black bar at the bottom of the window (the Auto updater?) the an 'install' is necessary. When I click it, it goes through the install process (always a 1.8 MB file) and says it was successful. But on return to the FC3 training window it still says 'install' necessary; and it seems to do this endlessly. Is it me or is there something wrong with the program? thanks for your thoughts on this.....
