Binary builds can be downloaded from the release page or the github CI artifacts from every single commit for 32bit and 64bit Windows.

    • 3 GB of free disk space
    • Visual Studio 2019 (or higher)
    • Meson
    • Ninja
    • Git

    Visual Studio must be installed with a Visual C++ compiler, supporting C++ libraries, and the appropriate Windows SDK for the target platform version.

    • Ensure Programming Languages > Visual C++ is selected

    If you need a copy of Visual Studio, the Community versions are free and work great.

    Install Python 3 and Meson via Conda

    Conda is our probably the best Python distribution for Windows. But you can skip the next steps if you have Python installed already

    Create a Python Environment for Radare2

    Follow these steps to create and activate a Conda environment named r2. All instructions from this point on will assume this name matches your environment, but you may change this if desired.

    1. Start > Anaconda Prompt
    2. conda create -n r2 python=3
    3. activate r2

    Any time you wish to enter this environment, open the Anaconda Prompt and re-issue activate r2. Conversely, deactivate will leave the environment.

    Install Meson

    Install Git for Windows

    All Radare2 code is managed via the Git version control system and .

    Follow these steps to install Git for Windows.

    Download Git for Windows

    Check the following options during the Wizard steps.

    • Use a TrueType font in all console windows
    • Use Git from the Windows Command Prompt
    • Use the native Windows Secure Channel library (instead of OpenSSL)
    • Checkout Windows-style, commit Unix-style line endings (core.autocrlf=true)
    • Ensure git --version works after install

    Get Radare2 Code

    Follow these steps to clone the Radare2 git repository.

    1. git clone https://github.com/radareorg/radare2

    Compile Radare2 Code

    Follow these steps to compile the Radare2 Code.

    1. Generate the build system with Meson:
    1. meson b --buildtype debug --backend vs2019 --prefix %cd%\dest
    2. msbuild build\radare2.sln /p:Configuration=Debug /m

    For Ninja (no visual studio interface required, just msvc compiler toolchain installed):

    Finally run this line to install r2 into the given absolute prefix directory:

    1. meson install -C build --no-rebuild

    Build options notes

    The /m[axcpucount] switch creates one MSBuild worker process per logical processor on your machine. You can specify a numeric value (e.g. /m:2) to limit the number of worker processes if needed. (This should not be confused with the Visual C++ Compiler switch /MP.)

    If you get an error with the 32-bit install that says something along the lines of error MSB4126: The specified solution configuration "Debug|x86" is invalid. Get around this by adding the following argument to the command: /p:Platform=Win32

    Check your Radare2 version: dest\bin\radare2.exe -v

    Check That Radare2 Runs From All Locations

    Note that in UNIX systems is just a symlink to the radare2 executable. So, in case you want to have it in Windows you can just copy radare2.exe r2.exe and add the directory into the system-wide PATH env var in the File Explorer settings.

    Notes about setting up the system-wide env var

    1. In the file explorer go to the folder Radare2 was just installed in.
    2. From this folder go to dest > bin and keep this window open.
    3. Go to System Properties: In the Windows search bar enter sysdm.cpl.
    4. Go to Advanced > Environment Variables.
    5. Click on the PATH variable and then click edit (if it exists within both the user and system variables, look at the user version).
    6. Ensure the file path displayed in the window left open is listed within the PATH variable. If it is not add it and click ok.
    7. Log out of your Windows session.
    8. Open up a new Windows Command Prompt: type in the search bar. Ensure that the current path is not in the Radare2 folder.
    9. Check Radare2 version from Command Prompt Window: radare2 -v
