   A compressed  .zip file is downloaded. You will need a program like WinRar to extract the compressed files
4. Open the .zip file and locate the folder named ‘macco-xxxx‘
5. Extract and place the folder into your Microsoft Flight Simulator Community Folder
   How do I find my community folder?
6. Start the sim and the installed addon will be available

Update

Same process as Downloading and Installing.
Make sure you delete the existing add-on file in your community folder before adding the newly downloaded one.

The MaccoSim desktop app is no longer in development, and we have therefore made the decision to shut it down.

If you still have it installed, you may experience issues in future, when there are breaking changes to the framework we used to build the app.

Contrail has many features and is always being updated, therefore we strongly recommend looking through their Tutorials to learn how to download, install and update your addons.
