Hi,
Following installation of v1.6 when using the 757-300 the FMC execute button remains lit all the time. Not only that - in some cases it does not function - when going to the settings/options page and for example turning the FO gauges off this option is not saved.
Could it be a corrupted installation? How should the aircraft (including the base pack) be installed if I have v1.5 installed already?

Thanks,

Shom
