For WES7E unit, please make sure the default agent on your Thin Client is at least 4.7 SP3 before using HTTPS protocol to do tasks. If it is an old agent, please update it with etiher FTP or sharefolder. After that you should be able to use HTTPS protocol to do the tasks.
For ThinPro 5, currently we only support cached deployment with HTTPS protocol. We already had plan to provide full image support for ThinPro 5, please stay tune for that.
