How does the installation work

[Tripple7]

Hello,
I want to order JFK and o'Hara but can you tell me how the installation works.
The add on manager is new to me and I just want to do things in the right order.
I also do not want to use any trial version but installing the software right away.

Thanks

There's a installation manual that comes with the products which covers exactly what you are asking:

- Look for fsdt_install_guide.pdf, found under the FSDreamTeam folder under the main FSX folder after the installation.

Basically, you download the installer, then you buy the product from within FSX using the Addon Manager, and it will activate immediately.
