Can't install older version of Cubase!

I am having issues with Cubase 10.0.5 like a lot of people, thankfully (I thought) I found a copy of my 10.0.14 installer, and also someone has posted a link to the 10.0.4 installer here.

The trouble is the installers both crash too!

Steinberg has been silent about the problems with the new version but can someone at least explain how to install the older versions and stop this unexpected time off work!

It looks like the library manager I have won’t run on 10.10.5, can I get an older version?
