If you:

1. Switch to Finder
2. Press Command+Shift+U
3. Launch Activity Monitor

Do you see any processes whose Kind is listed as 32 bit? You may have to add the Kind column to the view.

I know what the grid says. That doesn't mean a 32 bit plugin can't be installed; it would go in the same folder as aax64 plugins.
