Downloading Reko
Official releases are published every few months on Github and SourceForge. Users who can't or won't build Reko themselves can download the output of the AppVeyor integration builder. Naturally you can build the project from the sources: see "Hacking" below.

Installing Reko

Windows users
The following prerequisite software must be installed on your machine first:

• .NET Framework 4.7.2 (https://www.microsoft.com/net/download/dotnet-framework-runtime)

Download an MSI file from one of the places mentioned above, then simply run the installer.

Non-Windows users
The following prerequisite software must be installed on your machine first:

• mono version 5.14.0 (https://download.mono-project.com/archive/5.14.0/)

Note: we've been unable to test Reko with the most recent version of mono, 5.16.0, because a bug in said version makes it impossible to build. This has been reported in mono/mono#11663.
After installing mono, you can proceed by either downloading binaries directly from the integration build server, or by building Reko from sources (see Hacking below).

Documentation
To get acquainted with Reko's various features, you can read the user's guide. If you're interested in the internal workings of the project, see the wiki.

Getting support
You can report any issues you encounter or ask any Reko-related question on the issue tracker. You can also try the Reko Gitter.im chatroom. Reko is built by volunteers' efforts on their spare time, so adjust your response-time expectations accordingly.

Hacking
To build reko, start by cloning https://github.com/uxmal/reko. You can use an IDE or the command line to build the solution file Reko-decompiler.sln. If you are an IDE user, use Visual Studio 2017 or later, or MonoDevelop version 5.10 or later. If you wish to build using the command line, use the command
(provided you have msbuild installed). All external dependencies needed to build Reko are included in the external directory.
Note: please let us know if you still are not able to compile, so we can help you fix the issue.
If you're interested in contributing code, see the road map for areas to explore. The Wiki has more information about the Reko project's internal workings. Please consult the style guide.

Warnings and errors related to WiX
You will receive warnings or errors when loading the solution in Visual Studio or MonoDevelop if you haven't installed the WiX toolset on your development machine. You can safely ignore the warnings; the WiX toolset is only used when making MSI installer packages, and isn't even supported in MonoDevelop. You will not need to build an installer if you're already able to compile the project: the build process copies all the necessary files into If you do want to build an MSI installer with the WiX toolchain, you can download it here: http://wixtoolset.org/releases/

How do I start Reko?
The solution folder Drivers contains the executables that act as user interfaces: the directory WindowsDecompiler contains the GUI client for Windows users; MonoDecompiler contains the GUI client for Mono users; CmdLine is a command line driver.
