Photoshop Elements :: Can't Access Supplementary Editing With CS2

I was a user of Elements3 for a long time mainly because I liked that the catalog's "edit with" feature worked with Photoshop CS2.  I recently got a new PC with Windows 7 so I could not install PSE 3. I downloaded PSE9 trial version to see if all worked well and it was worth the purchase.  The problem I am having is that I cannot seem to get my Photoshop (CS2) as a supplementary editing option.  When I try it tells me this
 
But if I don't add it like it says, there is not a Photoshop option when I go to the "edit with" list.
 
I don't know if this is right, but from the little bit of research I did it thinks I am trying to add Elements again because the Elements program exe file starts with "Photoshop" so when it reads the Photoshop.exe file it thinks it is a duplicate.  I tried creating a copy and renaming the Photoshop.exe file which almost worked.  Elements allowed me to select it as a supplementary editor and afterwards Photoshop was an edit option.  I tried to edit a photo with it and while the program opened, it then got an error message and ended up closing before the photo came up for editing.
 
use Photoshop as my editor.  I really liked how I could edit in PS and keep a neat catalog of edited versions with the Elements versioning capability.  If I can't do it I probably won't end up purchasing the PSE9 program.
