Two users have encountered this - the documentation doesn't clearly state that we does not support Windows 7, so they get ugly errors about Studio missing the realm.node binary:

1. https://stackoverflow.com/questions/47198349/realm-studio-for-windows-javascript-error
2. https://github.com/realm/realm-js/issues/1527

We should probably give users a better error message if Studio is attempted started on an unsupported platform.
