I recently decided to learn Poser to compare it to Daz3D which I have been using for about a year now. When I buy a product from Daz it loads more or less automatically, but when I buy something for Poser it tells me to make sure I put it in the correct folders which apparently I am not doing correctly. 

I bought the DoDoDr bird character yesterday. In the Readme section it says to “copy the Runtime folder into the Poser Runtime Folder”. So I copied the Dodo Runtime folder and then went to: Applications/Poser 8/Runtime and pasted the Dodo Runtime folder there. But, when I go into the Poser Runtime Folder, while there is a new (DoDo) Runtime Folder there, it is just called “Runtime”. (If I click on that folder to see what's in it I find four subdivisions: Geometries, Libraries, Templates, and Textures. And each of these opens into Animals, Dodo, etc.) but Poser can't locate them.

I notice that I have a Poser 4 Folder with a Download/Runtime folder on my computer that must have come when I installed Poser 8. Is this relevant? 

What am I missing? Thanks in advance for any help.

I have Poser 8 (standard, not Pro) and am using it on a Mac GHz Intel Core i5 with 8 GB ram.
