In 5+ years I've used Poser on a Mac, I've never had an installer wipe out my existing default Poser Content runtime. The Smith-Micro Download Manager never did. It would just install whatever was new or newly updated. If I'd renamed any of the original folders or files, then the originals would be installed again without affecting the renamed versions. The 11.2 update from Bondware did the same thing.

As for the additional content, I unzipped those folders on a networked USB drive and installed the content by dragging the Runtime folder onto the default Poser 11 Content folder and choosing "Merge" (rather than "Replace"). That's basically how I install purchased, freebie, or custom-made content as well, except that I do that in a Runtime in a separate "My Poser Content" folder.

If you ever launch Poser and find that the library can no longer find any of your runtimes, you just need to use the little books with a + symbol icon to add them back.
