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.

1

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

2

Use the UnregisterExtension command to remove the unused extension.

3

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

Remove unused extensions to minimize potential errors and improve performance.
