According to Salesforce’s official guidelines, an administrator can delete a flow version that was installed from a managed package without uninstalling the entire package, only if the following three conditions are met:
B. The version isn’t the latest version of the flow in the org: The latest version must remain in the system.
D. The version is inactive: Active flow versions cannot be deleted.
E. The version has no associated paused flow interviews: If the flow has pending or paused interviews, it cannot be deleted.
Incorrect Options:
A. Deprecating a flow version alone does not enable deletion.
C. Scheduled actions apply to process builder and are not considered flow interview blockers directly in this context.
Reference Extracts from Salesforce Help Documentation on Managing Flows and Packages:
“You can delete a flow version installed from a package only if it is not the latest version, is inactive, and has no paused interviews.”
