After extracting the !HeuristicLab ZIP archive from this page into a new folder, double click on the file `HeuristicLab 3.3.exe` to start. == Sources and Version Control == At some point it might be beneficial for you to build against the code in our SVN repositories or fork the project on GitHub. For SVN you'll have to install ​Tortoise SVN because the build process makes use of one of its tools (SubWCRev). You need to have the bin folder of TortoiseSVN (usually C:\Program Files\TortoiseSVN\bin) in your PATH environment variable. Changing the PATH variable requires you to re-login to your Windows account to put them into effect. * SVN repository stable branch: ​https://src.heuristiclab.com/svn/core/stable (recommended: tested and reviewed changes only). * SVN repository main trunk: ​https://src.heuristiclab.com/svn/core/trunk (not recommended: frequent and unreviewed changes, moderate testing) * Full SVN repository: ​https://src.heuristiclab.com/svn/core (only for HL core developers! It is recommended to perform a partial checkout and exclude several or all branches, but not the branches directory itself) * GitHub: ​https://github.com/HeuristicLab/HeuristicLab (only releases are pushed to GitHub - note that we do not accept pull requests on GitHub, we only use it for publishing)
