I'm surprised that redirecting the install pathway to Poser 11 Content is ignoring its runtime folder and creating a new folder.  Or is that a folder of your own design?  I'm a little confused that Poser has generated a new folder, I would assume that it would dump the content into the folder you have specified.  When you did your installation, did you specifically instruct Poser to use the Poser 11 Content folder?  I'm fishing for some clarification.  Also, that 'My Library' folder doesn't belong there, the runtime folder within it is not technically linked to Poser in a correct way.  You have a runtime nested within a runtime.
