How do I enable the Use Adobe dialog option in Photoshop?
To enable the Use Adobe dialog commonly found in lower left of the Open, Open As, Open As Smart Object, Save, Save As or Place dialogs you have to have Version Cue enabled.
To enable Version Cue, go Edit > Preferences > File Handling and tick to enable Version Cue. Close the Preferences dialog, restart Photoshop and the Use Adobe dialog command option should now be available.
