Halion One sounds not available for Halion Sonic SE

Now I want to phase out Halion One. However I would like to use the same sounds in Halion Sonic SE.
The problem is that I can’t find these sounds in Halion Sonic SE.
Even worse I can’t even find them again in the Halion One as well when creating a new instrument track…

What is going wrong here?

What sound from Halion One are you missing in Halion Sonic SE?

As an intermediate step I would like to restore the Halion One player.

At this moment I cannot select any sound (empty) when creating an instrument track with an Halion One instance.

The Halion One sounds are present at three different locations.
One of them a sub folder of Cubase 5 is indicated when choosing Halion One at the locations panel of the MediaBay.
However when I open the Halion One instance from the instrument track (load preset) the other two folders are mentioned in the location tree.

How do I restore Halion One?

Personally, I would suggest switching to Halion Sonic SE now since Halion One is discontinued.

That said, I would suggest taking a look at this KB article for importing Halion One presets in Cubase 6: https://www.steinberg.net/en/support/knowledgebase_new/show_details/kb_show/installation-of-halion-one-presets-in-cubase-6/kb_back/2025.html?tx_p77sbknowledgebase_pi1[keyword_search]=HALionOne

I hope this information is helpful.
