Groove Agent SE 4 reinstalation

I have CUBASE 9.5 Pro. From Groove Agent SE some presets have disappeared. I tried reinstalling GA, but it did not help. So I uninstalled GA, but now I can not reinstall it. When I try to install it from GA SE 4.2.30 Update Installer, I will see: GA SE4 not installed. So how can I install GA again ?
