Quote - Yes, running the updater for each installation would be logical process considering it only targets that particular runtime.  It complicates the issue when keeping track of each installation.  Better to keep it simple and link all runtimes.

I've got at least a dozen runtimes. The reason I often have duplicate content is that every once in a while I realize that I need to re-organize, and it's easier just to reinstall any given runtime from scratch, than to try to find all the various files when deleting. But it's a big project, so I leave the old runtime that I'm re-installing linked (so I can still use it), until the the job is finished. It does mean, though, that when I'm loading old PZ3's, there may be a bit of a delay while Poser looks for the files, as they are in a different location. Otherwise, no problems.
