It's not possible to activate by the internet? Why?
I've done an internet activation within the past week and it worked perfectly.
With the FSX Gold package (it is not a new version, just the DVDs for FSX Deluxe and FSX Acceleration in the same box) you have to install the two FSX Deluxe DVDs.
You need to start FSX an Activate FSX with the FSX code in the box.
You then need to shutdown FSX without making any changes.
Load and install the Acceleration DVD
Start FSX and activate with the Acceleration code in the box.
