I'd be happy to help you with installing the mod for Flight Simulator 2002. Here are some general steps you can follow:
-Locate the downloaded mod file on your computer. It is usually in a compressed format like .zip or .rar.
-Extract the contents of the mod file to a temporary folder on your computer. You can use a file extraction tool like WinRAR or 7-Zip to do this.
-Once the files are extracted, look for any folders or files that are specific to the mod. In this case, you may find texture files for the Boeing 747-400.
-Navigate to the installation directory of Flight Simulator 2002. This is typically located in the "Program Files" folder on your computer.
-Look for a folder within the Flight Simulator 2002 directory that is related to aircraft textures or liveries. It may be named something like "Texture" or "Liveries."
Fun Games-Copy the texture files from the temporary folder (step 2) into the appropriate folder within the Flight Simulator 2002 directory (step 5). Overwrite any existing files if prompted.
Launch Flight Simulator 2002 and check if the modded textures are applied to the Boeing 747-400.
Please note that these steps are general guidelines, and the specific installation process may vary depending on the mod and version of Flight Simulator 2002 you are using. If you encounter any issues or need further assistance, feel free to ask!
