If you deploy Horizon Workspace multiple times after failures or upgrades, Horizon Workspace creates multiple extensions in vCenter. If you do not remove the unused extensions, errors can occur.


Log in as a vCenter administrator at https://vcenterFQDN/mob/?moid=ExtensionManager.


Use the UnregisterExtension command to remove the unused extension.


Look at the most recent heartbeat to determine the extension in use.

Remove unused extensions to minimize potential errors and improve performance.
