Make sure you have FSX SP2 or Acceleration installed.The installer will want to install some VS C++ runtime libraries after it installs the airplane. Did you allow that to happen?Someone else makes the 767.

It sounds like you didn't activate the JS41...If you run in full screen mode, for example, the first time you select the JS41 from the aircraft menu, the activation window should appear, into which you enter the activation code you have. This window was getting hidden by full screen mode in my case...I switched to windowed mode (alt + enter), selected the JS41, entered the code into the activation window when prompted...I then restarted FSX (as I have problems switching FSX from full screen to windowed then back to full screen...)Everything worked as planned...Hope this might help...Andrew
