Halion sonic installation confusion

[fenderchris]

I have the following installed and functioning on my Win-10 system:

Halion-5
Halion Sonic-1
Halion Sonic SE 3.1.10

Nuendo 6
Nuendo 7
Nuendo 8


My eLicensor indicates I have licenses for:

Halion-3
Halion-5
Halion Sonic-1

Nuendo 6
Nuendo 7
Nuendo 8

I also have Halion-2 Content installed, and Halion Sonic-3 (not working) but these may be there as the result of attempting to install these versions.

Given the licenses I've got, what versions of Halion Sonic and Halion Sonic SE should I have installed?

Should I be able to install Halion Sonic 2 or 3, or do I even need them given that Halion Sonic SE 3 is installed and running?


Very confused.
