I've followed the instructions (so far as I can tell) and I don't see the 'SU-25T' row under options:
Files installed here: C:\Users\Gary\Saved Games\DCS.openbeta\Liveries\Cockpit_Su-25T\English
I run 'training' pick a su-25 mission, hit escape, select options. Click into special, I see capto and etc, but no SU-25T row.
Thanks and apologies if it's pebcak.
Is it possible that the menu changes in DCS open beta 2.9.15.9599 caused an issue? VR / system options are now in the launcher. I don't see any general options prior to starting a mission / training and in the mission/training there's no row as mentioned above for the SU-25T
Disregard and appologies, it's the gear icon on the upper left. Everything is there. Thank you.
