MSFS Mod Manager

This is an external mod manager for the new Microsoft Flight Simulator to help you install and manage 3rd party addons.

I do not guarantee that this program will not accidentally delete all of your mods. Please keep good backups.

Features

Automatic Installation Detection

The program automatically tries to determine where the sim is installed, for you. No rooting around inside the AppData folder.

If the program can't automatically find the installation folder (you put it somewhere non-standard), you can manually select the location that contains the Community and Official folders.

This is normally %USER%\AppData\Roaming\Microsoft Flight Simulator\Packages or %USER%\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages unless you manually selected a different location.

Super Easy Mod Installs

The program will extract an archive, find all mods inside, and install them inside the correct folder automatically.

Enable and Disable Mods

Enable and disable mods on the fly without needing to re-download them.

Matching Theme

A custom-designed theme to roughly match the MSFS UI is optionally available.

No Need to Reinstall Anything

The program parses the native game files, so you do not need to reinstall all of your mods to take advantage of the features of this mod manager.

Mod Info

View info about a mod and quickly open the directory it is located in.

Backups

Easily create backups of all of your enabled mods, in case you need to reinstall your game.

Search

Filter mods as you type to help you find what you're looking for.

More To Come

This is still under active development. Pull requests welcome!

Usage

Just head to the releases page to download the latest installer. Or, if you want to live life on the edge, run the code from source, as described below.

Note: If you want extract .rar or .7z files with the program, you'll need to have 7zip installed.

If Windows complains that the application is untrusted, this is because the executable is not signed. A code signing certificate is needed to fix this, but they are rather expensive, and I can't justify the cost. The program is open source however, so you could build it yourself if you wanted, and the provided pre-built binaries are all created automatically on GitHub's infrastructure.

Running/Building From Source

Dependencies

First, install Python 3.6. Python 3.7 and Python 3.8 are not fully supported yet.

Next, install the dependencies with pipenv:

python -m pip install pipenv
pipenv install

Running

To actually run the program, use

pipenv run fbs run

or

pipenv shell
fbs run

Building

Building is done with the build.ps1 script.

To build a portable version of the program, run

./build.ps1

If you want a debug version of an .exe, add the -debug flag.

To build an installer version of the program, you first need to install NSIS. Now, run the same build script with the -installer flag:

./build.ps1 -installer

Creating a Release

1. Create a commit modifying the version number of src/build/settings/base.json.
2. In this commit, add the release notes to the commit body.
3. Tag this commit with the version number in the form of v#.#.#.
4. Push tag and commit to origin.
