Noel, there is an empty folder called "Panels" located in the Plug-Ins folder following that path.
I also have "C:\Program Files\
Adobe\ Adobe Photoshop CS6\Plug-ins\Panels with MANY sub-folders located inside (3D Engines, ADM, Automate, Digimarc, Effects, Extensions, File Formats, Filters, Image Stacks, Import-Export, Measurements, and Panels) plus 2 Firefox HTML Document files (gpl and README).
???
