How do I copy a plugin from CS4 to CS5?

[MiqsPix]

I have Nik Sharpener Pro 3.002 plugin with Photoshop CS4 but would like to install it in my new Photoshop CS5. Can anyone tell me if it is compatible with CS5 and if so how do I install it in my newer PS version please? I am running Mac OSX 6.

To install it you need to reinstall it. I'd remove CS4 from your PC also.

Or you could go in to CS5 preferences, select the additional plug-ins folder and take it to the CS4 location. Not saying it will work but you can try.

Different Photoshop versions work quite happily installed together.

Sometimes you can just copy the 88f file from the plug-ins folder sometimes you cant as it's using other files elsewhere, I think it needs the serial number again but I don'tknow for sure.

I have Nik silver efex and Viveza 2 both running on CS5 but I reinstalled them from the disk.
