Uninstall

AERR has no persistence outside its own folder.

Steps

1. Close DDS.
2. Delete AERR.dll from Win64\UnrealModPlugins\.
3. Delete the entire Win64\AERR\ folder (config, logs, saved state).

The game is untouched — no registry, no other file changes, no residual state.

What you lose

• Mixer recipes saved in the cookbook (unless exported as share codes first).
• In-game state from AERR scripts (rentals, purchased unlocks).
• Logs.

Your actual DDS save file is unaffected.
