I trook the electronic sledgehammer - fully uninstalled the program(me).
Re-installed in my laptop after successfully installing the Jeppesen software (at last).
This desktop is now, however, very sick - thanks to the Microsoft service technicians in Mumbai. Just turned it on this morning, monitors both showing as normal - but no mouse or keyboard control.
Rebooted and they came up.....but my Office suite is still deceased.
