If you go to PoserSoftware.com and click the downloads button you will find the link to Poser 11 files and if you go to that link you will find all the files have a date of 29 Oct 2020. So would be the latest files probably for both Poser 11 and 12.

The other way to do it is let Poser download the first set of content to the Included Runtime and copy that Runtime elsewhere and then install like you have in the past. Since each of the files you find at PoserSoftware.com is already "installed" you will have the same amount of work finding and moving each item no matter if you get the BIG Zip or let it be placed in the Included Runtime and then move that one.

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13
