BrainVoyager 20.2 for Windows

BrainVoyager 20.2 (QX 3.2) is our flagship product that provides a comprehensive, fast and elegant way to perform advanced neuroimaging data analysis and to create stunning visualizations. For more information, read the BrainVoyager 20 release blog post.

Installing the software-licensed version
. BrainVoyager uses a software-based licensing system and will not run without a valid license. In order to install BrainVoyager for evaluation or to update from an older version (BV 20.0) please use the following link:
setup_bv_v20.2_win-x64.exe (231.2 MB)

In case you update from a previous version with Python support, use this link:
setup_bv_v20.2_win-x64_python.exe (231.2 MB)

You can ask for a time-limited trial license to evaluate BrainVoyager with your own data. A trial license unlocks most features of a full license lacking only some optional components (no scripting and plugins). You need to accept the license agreement during installation.
To install the program, double click the downloaded installer executable (.exe file) and follow the instructions of the Installation Wizard. In case you have an older version of BrainVoyager (QX), close any running instance prior to installation. We highly recommend to deinstall any older version of BrainVoyager before running the installer. If the message "Do you want to allow the following program from an unknown publisher to make changes to this computer?" (or similar) appears during installation (User Account Control dialog), click "Yes", otherwise installation will not be performed.

If you have already a valid software license, you can continue to use BrainVoyager as before after installation and enjoy its new features. If you do not have a license, you will see a licensing screen after starting the software. To activate (unlock) a time-limited trial version, you need to send an email to “licensing [at] brainvoyager [dot] com” containing the displayed “Hardware-ID” and additional information for registration (name, institute/lab, mail address). This email is prepared automatically by clicking the “Prepare Email” button in the displayed dialog (see image below). Usually within 1-3 days you will receive a license key and a license name/ID (e.g. TSKF307BC88-PETER-SUGAR). After entering this information in the licensing dialog, the software will be activated and it is ready to use for 30 days. More details about the licensing and activation process can be found on the page BrainVoyager Software Licensing.

In order to get the full version of BrainVoyager (after evaluating the trial version), please send an email to “sales [at] brainvoyager [dot] com” to purchase a license. The full version unlocks the program permanently (or for a certain duration) and enables some features that are disabled in the trial version, including scripting and plugins. If you purchase the full version of BrainVoyager, you will get a key that unlocks all licensed features and the software can be used as long as requested in the purchased license.
The installer will put the program folder “BrainVoyager” in the “C:\Program Files” directory (“C:\” is the usual example of the operating system drive, it might be different in your case). The 32-bit version of BrainVoyager (not recommended but available on request) will be installed in the “C:\Program Files\BrainVoyager32" directory. Since BrainVoyager QX was installed in “C:\Program Files (x86)” the new version can be installed side-by-side to an existing BrainVoyager QX 2.8 installation without interference. Also scripts and plugins will be installed in directory “Documents\BVExtenstions” instead of the old directory “Documents\BVQXExtensions”.

Installing the hardware-licensed version. During a transition time, the old hardware-based licensing system (Hasp dongle) will be available, but we strongly advice existing users to move over to the new software licensing. In case you have a dongle-based (Hasp) license that is valid for BrainVoyager QX 3.X, you can download a copy of BrainVoyager 20.2 / QX 3.2 for 64-bit Windows below.
setup_bvqx_v3.2_win-x64.exe (234 MB)
setup_bvqx_v3.2_win-x64_python.exe (238 MB)

Note that the hardware-licensed version of BrainVoyager QX works only in combination with the HASP licensing system, i.e. you need either a HASP dongle for a single user license or a HASP floating network license. If you use a single-user license, a device driver has to be installed in order to access the local HASP dongle.

Python on Windows
BrainVoyager 20 supports an embedded Python interpreter as a new programming language for scripting and plugin development. Python support is marked as experimental in BrainVoyager 20.0 since some features are missing for a complete integrated development environment, most notably debugging support and a more powerful multi-document editor.
Windows does not come with Python so it needs to be installed on your computer in case you want to use Python in BrainVoyager. The full software and hardware licensed version of BrainVoyager are available in two variants (the trial version does not support Python). If you are not interested in using Python, it is recommended to download the installer without the “python” substring. Note that you can always switch to the Python version at a later stage. If you intend to use Python, you need to install the variant with the “python” substring.
For BrainVoyager 20.2 there must be a specific Python distribution installed located at a specific place otherwise the Python variant of BrainVoyager will not start. BrainVoyager supports Python 2.7.x (not 3.x) and it is highly recommended to install the WinPython distribution that can be downloaded using this link:

or from the original WinPython web site. WinPython comes already with the major scientific packages (such as numpy and scipy) and it can be installed in a folder without affecting any other (existing) Python installation. When running the WinPython installer, select “C:\” as the installation directory. After installation you should then have the following folder on your computer:


In order that BrainVoyager finds the installed Python interpreter, WinPython not only needs to be installed in the root directory (usually “C:\”) but the directory need to be also in the system PATH variable. Please make sure that the following folders are added to your system environment PATH:

Path=C:\WinPython-64bit-\python-2.7.10.amd64;C:\WinPython-64bit-\python-2.7.10.amd64\Scripts;[...other paths...]

BrainVoyager with Python support should now start successfully and offer a python console and python developer environment. To start with Python, consult the provided examples in the “BVExtensions/PythonScripts” and ”BVExtensions/PythonPlugins" directories that are available in the Python IDE.
System requirements
Version 20.2 of BrainVoyager (version 3.2 of BV QX) is fully compatible with Microsoft Windows 7, 8, 8.1 and 10. While we provide a 32-bit version on request, we strongly recommend to use the 64-bit version. While most functions of BrainVoyager run with modest working memory demands, a minimum of 2 GB is required and 4 GB (or more) recommended. To benefit from 3 or more GB of working memory as well as from OpenCL support, the 64-bit version of BrainVoyager is required.
Sample data
If you want to learn basic and advanced features of BrainVoyager, it may be useful to start with example data sets, which are also used in our BrainVoyager Training Courses. The installer on this page does not contain sample data. To download example data sets, click the "Sample Data Web Page" item in the "Help" menu of BrainVoyager or visit the example data sets page with your Browser. The analysis of the "Objects" data set is described in detail in the BrainVoyager Getting Started Guide
The User's Guide (available locally as well as online) provides general information and can be easily invoked by clicking the "User's Guide" icon in the main toolbar or by clicking the "User's Guide" item (or User’s Guide (online) item) in the "Help" menu. Several PDF files introducing various topics are also placed in the BrainVoyager folder after installation, including the "Getting Started Guide". If you are upgrading BrainVoyager, you may want to check out the "News" section of the User's Guide. We highly recommend to read the release notes (see "Help" menu) to learn about new features, enhancements and bug fixes. The User's Guide and additional documentation is also available online. If you have any questions, suggestions or bug reports, please send an email to "support at BrainVoyager dot com".
