Error with London City Airport Addon Installation: Scenery.cfg File Issue

Your experience with the London City Airport addon installation in Microsoft Flight Simulator X is quite concerning, and I can understand the frustration it must have caused. The error you've encountered is a common one, and it typically revolves around the configuration of the addon within the simulator. Let's dig into the details and work through the possible solutions.

1. Understanding the Error
The error message you received, "...Scenery.cfg file error. local scenery directory (Addon Scerery\scenery). in scenery area .115 not found...", specifically points to an issue with the scenery.cfg file. This file is vital in mapping your addons, and if it's incorrectly configured or missing a pathway, FSX won't recognize the addon files.

2. Detailed Solutions
Given that you've tried both the auto-installer and manual methods, let's go through a more detailed set of steps to resolve the issue:

1. Verify Scenery Path Configuration: Open the scenery.cfg file (usually found in the main FSX folder) and ensure that the path mentioned for the London City Airport addon is correct. The path should lead to the directory where you've installed the addon, which can be downloaded here.
2. Check for Misspelled Directories: The error message contains "Addon Scerery," which may be a typo. Check for misspelled directories and correct them if necessary.
3. Reinstall the Addon: If manual adjustments do not work, completely uninstall the addon and then reinstall it using the auto-installer. Remember to run the installer as an administrator.
4. Ensure Simulator Compatibility: Confirm that your version of FSX is compatible with the addon. Sometimes, third-party addons require specific versions or patches to function properly.

Note: The solutions provided here may also be relevant for other platforms such as Microsoft Flight Simulator (released in 2020) and X-Plane 12, if applicable.
