Lost All Of My Custom Recipes

[Egregius ([Greg] (Micro 4/3 + Win11))]

Do follow John-M’s guidance. I hope your recipes are still on your computer somewhere. But it’s possible that if you upgraded the Nik Collection on your computer you truly did lose your custom recipes in the process. In which case you’d need to restore them from a backup. For reference, see this and the posts that follow:

Presets and Recipes

I lost about a year’s worth of my custom presets and recipes when I upgraded, since I expected this upgrade to behave like previous Nik upgrades and preserve them. Please suggest to people that they export their custom presets and recipes before upgrading.

DxO’s official article on this is here:
