The RMTK is a python toolkit separate from the OpenQuake-engine. Although a direct installer is now available for the
OpenQuake-engine for Windows, a similar Windows installer is not yet available for the RMTK.
For working with the RMTK on Windows systems, our recommendation would be to download our
VirtualBox appliance which comes with the OpenQuake-engine and several other toolkits (including the RMTK) pre-installed and pre-configured. You'll first need to download and install the latest version of
VirtualBox for Windows, and then import the OpenQuake VirtualBox appliance. After importing and booting the (Linux-based) virtual machine, you should find the RMTK installed at /home/openquake/GEM/RMTK/
