I have CS5 Design Standard ( without extended Photoshop) and I need to get the PDF help files for the component applications. I have tried entering CS5 Help Files and variations of that theme in the search box here at Adobe forums and get many things about CS6 and no Help files for CS5.

Here's another link for Ps CS5 PDF help:
And for Creative Suite with links to the CS5 point products:
