System Requirements

Starting from 3.3.16 HeuristicLab requires a 64-bit operating system to use all features. Specifically, the OR-Tools integration is affected. You can still run HeuristicLab in 32-bit environments, but you have to remove Google.OrTools.dll from the folder containing the HeuristicLab.exe file before you start it.

HeuristicLab is based on the Microsoft .NET Framework. In order to be able to run HeuristicLab properly, you have to download and install the following software package:

• ​Microsoft .NET Framework 4.6.1

Please note that HeuristicLab also runs on Linux with ​Mono but we are only able to provide limited support. Check out the HeuristicLab and Mono Howto for more information.

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.
