Installing the OpenQuake Engine on Windows#

The OpenQuake Engine can be installed on Windows with the universal installer (recommended if you plan to develop GMPEs) or with a traditional .exe installer which can be downloaded from . The .exe installer uses Python 3.10 and we recommend to use the same Python version also with the universal installer.


Requirements are:

  • Windows 10 (64bit)

  • 8 GB of RAM

  • 4 GB of free disk space

Windows 7 and Windows 8 are not supported. That means that we do not test such platforms and they engine may or may not work there. Also, it may work for small calculations and hang for large calculations, as it has been reported by a few users. For large calculations (i.e. any calculation in the hazard or risk mosaic) we recommend to use a Linux server.
