Quote - No the texture is under main runtime/libraries/pose and also under main runtime / textures?

We don't know what you mean by "main runtime", I'm afraid.

Look in your windows file system to see the full path of where you installed that content.
Then look in Poser to see the full path of the Library folders you are viewing.

My guess is that these two are not the same. Hence you can't see the content in the Poser library.
