I upgraded to 8.1.6 yesterday. When I launch workstation it wants me to upgrade. The link that it provides to download the new version appears to be broken.
This has been fixed in the workstation version shipped with 8.1.5. The irony is you have to update workstation for this update link to work. http://192.168.10.2:8088/web/perspective-workstation should be the appropriate link in your situation
