Received quickly, I installed the game without difficulty on a PC (in administrator mode) under SEVEN, without problems; the game is fluid with a frame rate to 30FPS, but I have a robust configuration, and that's why I came back to FSX, having experienced previous versions! Activation was done successfully with the key provided. The box contains 3 DVDs with the DVD pack extension / accelerator. For cons, I have not installed, because I do not know if it is compatible under SEVEN. The game works well, beautiful scenery, I will add to it (next AMAZON purchase) a Thrustmaster Hotas X PC T.Flight Manette Gas and Flight Simulator PC 12 buttons, replacing my side winder precision PRO! Overall, very satisfied with my purchase I touched 20.33 euros, 2.99 euros postage. I also installed the Acceleration pack, no problem: the updates are SP1 and SP2 on the DVD ROM. The pack verifies that SP1 is present, if not: it installs SP1 and SP2. We must of course register online on returning the wrench provided, to enjoy ...
