Just to add my experience...
I just migrating to a new PC and had this issue as well. standard CT_Neo, missing for Crestron App.
I uninstalled v2.19, installed v2.15 then v2.17 directly from their exe's, and then used MI to update to v2.19 (along with updating the CreDB and D3 to the latest).
This fixed the issue for me...
I wonder if v2.19 (and maybe v2.17) have missing CT_Neo files???
