the View/Options.../Plugins dialog tab shows and lets you setup search paths, not plugins
there's no way you can see any plugins on that dialog, be that DSSI or any other type, as it is not meant to show any but a list of directories, not files.
another thing you might have confused is that Win32-VST plugins (.dll) are searched via dssi-vst-scanner, a component of dssi-vst, which search path is given by VST_PATH environment variable.
the search paths in the plugins tab on the options dialog above does not apply here. the only relevant setting is the one related to DSSI plugin type, where the exact dssi-vst proxy-plugin should be found.
