Quote - I am wondering does one need to re install content using the bit rock installer or can I just copy from my runtime folder & I think it was mentioned that one has to create a new location?

I usually install to a test library, then I rearrange the Poser library as necessary.  I also test the materials etc there.

After I'm satisfied, I move the test library on top of the main library.

You can use the exe installers to do this as well.
