Groove Agent SE5 not loading with Cubase 10

Hi All
I just downloaded Cubase 10.0.20 and was expecting Groove Agent SE5 to come with it as per the specs on the Steinberg website. However, it only seems to load Groove Agent SE4 when I open it. Any ideas or thoughts as to how I can get the latest Groove Agent SE?

Many thanks

Groove Agent SE 5 is part of Cubase 10. If you are upgrading from a previous version of Cubase, you must download and run the full installer for your product. Update installers can only be used to update from a previous release of a version to a later one (for example Cubase Pro 10.0.15 to Cubase Pro 10.0.20).
