Yes, Halion Sonic SE3 is included with Cubase Elements.
Cubase Elements contains over 1000 sounds totally (not only for HSSE, also Groove Agent SE is included).
Although you can install the free HSSE version, the free version does not contain any sounds (but sounds are included with Cubase Elements).
You can however try the trial version for Cubase Elements free for 30 days here:
If you get Cubase Elements it will either install HSSE3 or update your existing HSSE3 installation, so it should not matter if you uninstall HSSE3 or not.
(Regarding your other thread, you only need the full 3.4 installer, not the older 3.1. But the free version doesn’t contain any sounds anyway.
I wrote an answer in your other thread too, but for some strange reason it got stuck into moderation.)

Ok, that’s what confused me. If you look at the screenshot I reposted in another thread about the “Some audio files missing” thing:
… why is it showing the names of some instruments/sounds like “Turkish Perc kit 01” ??? Mine shows in that same Load space instruments like “Acoustic Grand Piano” etc etc.
Does free Halion list the names of the sounds but doesn’t actually include them?
Free version contains sounds, but it often seems to not find them by default if you install the sounds to a different directory than the default.
It contains a basic set of GM sounds. So, it’s useful if you use a DAW that doesn’t include a General MIDI Synth. Samplitude Pro is one example of such a scenario.
The sounds should be in ProgramData\Steinberg\Content. If you set a non-default location for the sound data, move the files from there to the location you set.
The free HALion Sonic SE download version does not contain any content.
I you want to try HSSE out, why not get the Cubase Elements Trial version (linked in a post above)? I suppose all content for HSSE is in that trial so you can try both HSSE and Cubase Elements in one go.
