Unable to install Cubase 6 on Sierra

I cannot install Cubase 6 with Sierra, even with the Steinberg_Application_Installer_Tool.
I get an error message (see attached file)

Could you guys help ?

I don’t know if they update the older version installers. If they do it would take them some time.

Can you find the specs on cubase 6? Probably says the last OS that works.
