CS4 About installing the `Optional Plugins' 64 or 32 bit

Question

Can anyone tell me from experience if when installing the `Optional Plugins' found in the `goodies' directory of install discs or from online sources by adobe, does it matter which  photoshop `plugins' directory you use, or do you need to drop them in both?
(I'm particularly interested in the contact sheet II plugin)
On 64 bit systems (Using CS4) you have one 64 bit version of PS and one 32 bit version.  Both have the dirctorires mentioned in the instructions found in:
`Photoshop CS4 and Photoshop Extended CS4 Read Me for Optional Plug-Ins, Extensions and Presets' *.pdf instructions.
But I don't see any mention of 64 or 32 bit in relation to placement of the `optional plugins'.

Answer 1

Hey Harry, I think he knows (Chris wrote part of the program).
I believe what Chris is saying is that:
1.  Only 32 bit plug-ins work with 32 bit Photoshop, and only 64 bit plug-ins work with 64 bit Photoshop.
2.  There are plug-ins in the package for each of the variants, 32 bit and 64 bit.
3.  The 32 bit plug-in(s) need to go under the install area for the 32 bit Photoshop, which is rooted at (on a 64 bit system):
     C:\Program Files (x86)\Adobe\Adobe Photoshop CS5\Plug-ins
4.  The 64 bit plug-in(s) need to go under the install area for the 64 bit Photoshop:
     C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Plug-ins
If you look in the PSCS5OptionalPlugins_Win_en_US.zip file it's pretty obvious which of these are in what subfolder (look for Win32 and Win64 subfolder names).
Note also that the ReadMeCS5_OptionalPlugin.pdf file in the base folder inside the zip file does give instructions.
