Due to an existing bug, the delete button on the License Server Administrative Sets page may not function.
When this issue occurs, you can't delete created License Server Administrative Sets from FlexNet Manager for Engineering Applications web UI.

Steps to Reproduce

1. Create a new License Server Administrative Set from Admin > Add License Server Admin Set.
2. Select the created license server administrative set, then click the Delete button.

Workaround

Use the SQL Server (FlexNet Manager for Engineering Applications Admin Database) script attached to this article. Modify the line SET Name = 't3' so it uses the name of the set you'd like to delete.
