There was a message in the B777 forum saying:
"Captains,
It appears that some of you are not aware of ACE existance and/or purpose.

The ACE (stands for Aircraft Configuration Editor) is a free utility that helps you with CS products."

I am well aware of ACE and used it for my liveries for instance.
BUT today I needed it to configure a flight, wanted to change lbs to kg, add passengers and cargo and SAVE it.
Unfortunately there was no button to be found anywhere to SAVE my changes   

Please help me to find a way to save those settings and use them for the next flight.

THANK YOU!

Thank you, Mark, for that information!
I found it now and all works as it should....

However, my question was based on the included tutorial where on page 2 Tom Beckett refers to the ACE for those settings (see pic attached).
That tutorial was written in 2014 and never updated to incorporate changes done in later versions.

So, again, thank you very much and all the best for the upcoming holidays and the new year 2022!
May it become the best year ever for you and your loved ones, in particular after this pandemic and its consequences for all of us.
Cheers
Juergen
