We are aware of this issue. What may help is to make sure that your
PYTHONHOME environment variables are pointing to Anaconda's installation directory. So if you installed Anaconda in
C:\Users\Marie\Anaconda3, then set both of these variables to that path. On Windows10, click 'start', search for and start 'Advanced System Settings', click the 'Environment Variables' somewhere near the bottom.
A future update will do this for you automatically, but at the moment an issue with Microsoft's packaging system 'vcpkg' prevents us from generating a new installer.
