To delete a flow version (especially one installed from a managed package), several conditions must be met:

A. The flow must not be referenced by another flow. Dependencies block deletion.

B. The flow version must not have any paused flow interviews (these are tracked in Setup).

C. There should be no scheduled actions (e.g., scheduled paths or future-dated flow execution).

Incorrect Options:

D. Deprecation only hides a version; it does not permit deletion.

E. Inactivity is required for deletion, but on its own does not guarantee deletion unless the above conditions are also met.

Reference Extracts from Salesforce Process Automation Study Guide:

“A flow version cannot be deleted if it is referenced, has paused interviews, or has pending scheduled actions.”

“Only inactive and unreferenced flow versions with no active execution can be removed.”
