SystemModeler requires access to a C++ compiler to run simulations. On Windows, SystemModeler supports the C++ compilers bundled with Microsoft Visual Studio editions 2013, 2015 and 2017.

If a C++ Compiler is already installed

  1. Start SystemModeler. SystemModeler will automatically detect the C++ compiler and set it as the default compiler.
  2. Verify that the compiler setup was successful.

In case of error messages, please try setting up the compiler manually.

If a C++ Compiler is not yet Installed

  1. Start SystemModeler. A dialog prompting you to download one of the supported compilers appears:
    SystemModeler no compiler
  2. Select “Check Online”. The “Install Compiler” screen appears.
  3. We recommend selecting Visual C++ Build Tools 2017. Click “OK” to confirm your selection. The selected version of Visual Studio will begin to download.
  4. Follow the prompts to install the selected tools.
  5. Once the Visual Studio installation is complete, restart SystemModeler. SystemModeler will automatically detect the C++ compiler and set it as the default compiler.
  6. Verify that the compiler setup was successful.

In case of error messages, please try setting up the compiler manually.

Alternatively, free editions of Visual Studio can be manually downloaded and installed from the following links:
