As explained on the Cloud9 product web page here:
http://www.fsdreamteam.com/products_cloud9.html"IMPORTANT"
If the Cloud9 product you purchased doesn't have an FSDT updated installer yet, you have to install the Cloud9 product first, then update the Stand-alone Addon Manager"
So, first update the Stand-alone Addon Manager for FSX, after installing Orlando, which is a Cloud9 product that doesn't have an FSDT installer.
Then, check if you see that message again. If you do, it means you really don't have SP2 ( or Acceleration Pack ) installed. Just SP1 is not enough: all our current products requires SP2 or the Acceleration Pack.
