How to Fix PMDG 777 Activation Issues and Landing Gear Problems
If you are a fan of the PMDG 777, you may have encountered some issues with activating the product or getting the landing gear to work properly. In this article, we will show you how to solve these common problems and enjoy flying this realistic and immersive aircraft.
Some users have reported that they are constantly asked to enter the activation code for the PMDG 777, even after they have successfully activated it. This can cause the aircraft to load with no gauges, no gear, no cockpit sounds, and no system initialization[^1^] [^2^] [^3^]. This is usually caused by a problem with the Windows User Account Control (UAC) settings, which prevent the PMDG 777 from writing to the registry.
To fix this issue, you need to make sure that you run FSX as an administrator, and that you have full permissions to the FSX folder and its subfolders. You can also try disabling UAC temporarily or adding FSX to the UAC exception list. If you still have activation issues, you should contact PMDG support and provide them with your purchase information and a screenshot of the activation window.
Landing Gear Problems
Another issue that some users have experienced is that the landing gear does not extend or retract properly, or that it appears retracted when the aircraft is loaded. This can be caused by a corrupted panel state file, a missing highmemfix setting in the FSX.cfg file, or a cracked version of the PMDG 777[^2^] [^4^].
To fix this issue, you need to make sure that you have a valid and updated version of the PMDG 777, and that you do not use any cracks or modifications that may interfere with its functionality. You also need to check your FSX.cfg file and add or edit the following line under the [GRAPHICS] section:
This will prevent FSX from running out of memory and causing graphical glitches. You also need to delete any corrupted panel state files from the PMDG\\PMDG 777\\PanelState folder, and load a default panel state when starting a flight. You can also try resetting the landing gear by pressing G twice or using the manual gear extension lever in the cockpit.
The PMDG 777 is one of the most advanced and realistic add-ons for FSX, but it also requires some attention and care to work properly. By following these steps, you should be able to fix any activation or landing gear issues that you may encounter, and enjoy flying this amazing aircraft.
