Reinstall Rhinio for MAc in Read only mode

I need to use Rhino as a viewer for files sent to me by my architect.

I had previously had Rhino installed and it was working fine after the free 90 days trial in read only mode.

I had to transfer to a new macbook and i deleted Rhino thinking I can do a fresh reinstall.

Now when I install it, Rhino says trial is over and I have to buy a license.

I am not designing in Rhino, I only want to view the files sent by my architect.

How do i reinstall Rhino as a viewer

thanks fo rthe help in advance,

kind wishes

An expired eval license can be used Stand-alone and Rhino will run without the ability to Save or Export.
