Gigapixel AI 6.1.0 not showing up in PS CS5 Topaz filters. Works OK in standalone mode

Installed GigapixelAI 6.1.0 and it seems to work OK in standalone mode but I can’t get it to show up in my Ps CS5 Topaz filter menu.

It won’t show up there, it should be under File>Automate - that’s if CS5 supports it.
