Python 2

With Python 2 officially unmaintained, the last stable release of Binary Ninja with support for it will be the 2.2 stable release.


  • Have you searched known issues?
  • Have you tried rebooting? (Kidding!)
  • Did you read all the items on this page?
  • Then you should contact support!

Bug Reproduction

Running Binary Ninja with debug logging will make your bug report more useful.

./binaryninja --debug --stderr-log

Alternatively, it might be easier to save debug logs to a file instead:

./binaryninja -d -l logfile.txt

(note that both long and short-form of the command-line arguments are demonstrated in the above examples)

Troubleshooting Plugins

Disabling Plugins

Disabling plugins can be a quick way to diagnose whether some unexpected behavior is caused by Binary Ninja itself or a plugin. Simply launch the process with the extra command-line option -p to disable all user plugins at load time. Note that repository plugins are currently not disabled with this switch.

Other Steps

While third party plugins are not officially supported, there are a number of troubleshooting tips that can help identify the cause. The most important is to enable debug logging as suggested in the previous section. This will often highlight problems with python paths or any other issues that prevent plugins from running.

Additionally, if you're having trouble running a plugin in headless mode (without a GUI calling directly into the core), make sure you're running the Commercial version of Binary Ninja as the Student/Non-Commercial edition does not support headless processing.

Next, if running a python plugin, make sure the python requirements are met by your existing installation. Note that on windows, the bundled python is used and python requirements should be installed either by manually copying the modules to the plugins folder.

License Problems

  • If experiencing problems with Windows UAC permissions during an update, the easiest fix is to completely un-install and recover the latest installer and license. Preferences are saved outside the installation folder and are preserved, though you might want to remove your license.
  • If you need to change the email address on your license, contact support.

Running as Root

Binary Ninja will refuse to run as root on Linux and MacOS platforms (this is partially enforced by the usage of an embedded QWebEngine which will not run as root). You can work-around this issue by either running as a regular user, or forcing BN to launch but you will need to also disable active content. If you try to use su or another similar tool, make sure that user has permission to the X11 session.


  • If the GUI launches but the license file is not valid when launched from the command-line, check that you're using the right version of Python as only 64-bit Python 2.7, or 3.x versions are supported. Additionally, the personal edition does not support headless operation.

Database Issues

  • BNDBs may grow in size after repeated saving/loading. While a future update to Binary Ninja will implement this optimization internally, this unofficial script may be useful for shrinking the size of a BNDB. Please ensure you backup your database prior to trying that script as it is not an officially supported operation.


The below steps are specific to different platforms that Binary Ninja runs on. See the FAQ for currently supported versions.


  • While Windows 7 is not officially supported (by us, or Microsoft for that matter), it's possible to have Binary Ninja work if all available windows updates are installed as a library pack update somewhere in the updates is required for us to run.
  • If you install Windows without internet access and have never run windows updates to install an update, you may have an incomplete windows certificate store. You'll see errors when attempting to update about CERTIFICATE VERIFICATION FAILED. If that is the case, you can either use something like certutil.exe -generateSSTFromWU roots.sst and then manually copy over the DST and Amazon certificates into your root store, or wait until the next time you have an update from Windows Update which should automatically refresh your certificate store.

Some Graphics Chipsets

Some graphics chipsets may experience problems with scaling resulting in the top menu disappearing. In that case, the simplest fix is to set the environment variable QT_OPENGL=angle.

VirtualBox and VMWare

If you're using Windows virtual machines within virtualbox or VMWare, you may have trouble with the 3d acceleration drivers. If so, disabling the 3d acceleration is the easiest way to get BN working.

You may also manually create a settings.json file in your user folder with the contents though using the plugin manager may also have problems:

    "updates" :
        "activeContent" : false


Xcode Installed Python 3

If you're running Catlina MacOS with the Python 3 installed by XCode and wish to use that version of Python with Binary Ninja, you'll need to do the following:

  1. Set the PYTHONHOME environment variable for your user to the following: PYTHONHOME=/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7
  2. If you have an existing settings.json in ~/Library/Application Support/Binary Ninja/ merge the below, or create it with these contents if it does not exist:
    "downloadClient" :
        "providerName" : "QtDownloadProvider"
    "python" :
        "interpreter" : "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/libpython3.7.dylib"

Old MacOS

While OS X is generally the most trouble-free environment for Binary Ninja, very old versions may have problems with the RPATH for our binaries and libraries. There are two solutions. First, run Binary Ninja with:

DYLD_LIBRARY_PATH="/Applications/Binary" /Applications/Binary\

Or second, modify the binary itself using the install_name_tool.

Non-brew installed Python 3

One potential issue for installed Python 3.x versions on MacOS is that the bundled certificates do not align with the native certificate store. This results in an error while attempting to download updates using the python provider. One of the following may fix this:

pip install --upgrade certifi


open /Applications/Python\ 3.6/Install\ Certificates.command


Given the diversity of Linux distributions, some work-arounds are required to run Binary Ninja on platforms that are not officially supported.

Common Problems

Below are a few of the most common problems with Linux installations:

  • Some unzip utilities do not maintain the +x executable bit on files when extracted. To fix this, we recommend:

chmod +x binaryninja/*.so.* chmod +x binaryninja/plugins/*

  • Permissions: ensure that the user you are running Binary Ninja as has write permission to ~/.binaryninja as it needs to be able to update user settings and other files in this folder.


Debian requires one package be manually installed to support the emoji icons used in the Tag system:

apt install fonts-noto-color-emoji

Headless Ubuntu

If you're having trouble getting Binary Ninja installed in a headless server install where you want to be able to X-Forward the GUI on a remote machine, the following should meet requirements (for at least 14.04 LTS):

apt-get install libgl1-mesa-glx libfontconfig1 libxrender1 libegl1-mesa libxi6 libnspr4 libsm6

Arch Linux

  • The only known issues with Arch linux are related to not being able to automatically find the appropriate libpython. Specifying your own custom path to the in the Settings pane under the Python Interpreter setting should solve any issues.


To run Binary Ninja in a KDE based environment, set the QT_PLUGIN_PATH to the QT sub-folder:

cd ~/binaryninja
QT_PLUGIN_PATH=./qt ./binaryninja
