Thanks, Poser - 3D Rendering & Animation Software (posersoftware.com);
So, you're saying, I can download P11 at your link.  Hopefully, it's just a download and not an immediate download/install.
That's because I'm still keeping the old computer free of internet access.  I mean, I can download (only) to the machine
I'm using here, and then transfer the download to the old computer.  I wouldn't want it installed on this machine here.
