Where do dll files for plugins go under Vista-64 for CS3?

I copied two dll files that CS3 complains are missing into several places within the C drive for Vista-64, and none seem to work. The missing ones are MSVCRT10 and IJL15. I called Adobe but they want $39 to talk to anyone about any CS3 issues!! [Just because CS4 is out now.] Here are some places that I tried:
\windows\system32
the plug-ins directory

Where should they be??? Thanks for any hints.

The advice in the item pointed to by this URL tells one to put them in the \System32 folder. I had already tried that before I posted the query yesterday. After a lot of experimenting and finally reading the files on the CS3 disk, I found that they have to be located in the Photoshop directory itself. When placed there, everything is happy!!

Thanks for the leads - I'm now greatly relieved.
