When trying to start the “Deploy OVF Template” wizard from vSphere Web Client 6.5, you may meet this error:
This version of vCenter Server does not support Deploy OVF Template using this version of vSphere Web Client. To Deploy OVF Template, login with version 22.214.171.124 of vSphere Web Client.
This error was reported for earlier versions of vSphere 6.5 and VMware released this KB article. VMware added a fix in VMware vCenter Server Appliance 6.5 b.
The issue reappeared in some cases after a new upgrade to the latest vSphere 6.5 Update 1 and it’s treated in the second KB article.
