Ryan thank you so much for your rapid reply and help.
I have installed SP1c update and now have the aircraft installed and running.
Yes I bought the addon when it first came out last summer, but since my old computer did not run FSX at all well I held off until I got a faster computer which could run FSX. Got a new computer this week and hence have only now installed the aircraft.
Again I am very appreciative of your kind assistance, many thanks.
Very best regards,
Larry Manderson.
