Delete
The Delete button in the Workbench License Manager is enabled when you have one or more host IDs and/or license files selected in the left pane, and produces a confirmation
dialog to delete licenses from your local license database, as shown below.
Figure 133. Delete licenses confirmation
Click Yes to delete the license(s), or No to leave the local license database unchanged.
NOTE: Following a delete, you may need to click the 
Refresh button in order to update the left pane contents. Note that if the selected “host ID” folder contained only a .license
file, the entire folder is removed with a delete. However, if the folder contained other files (or subfolders), only the .license
file is actually deleted, but it will no longer appear in the left pane.
