Please read this blog if you are running VMware Horizon less than version 7.10.
The Adobe Flash End of Life on 12/31/20 will affect you and your choices are:
Hi, I did install a new VM temporarly until all is updated to Horizon8. The new VM is not member of a domain (workgroup) it is working with Firefox V70 portable without dns entry's. With that, it is save and the hole administration with View 7.x is working with flash fine.
I was running 7.10 and when upgrading to 7.13 I found that there is still no way to set a pairing password for the Security Server in the HTML5 interface. I worked around this by using a Windows 7 machine and rolled back the date 1 year for Flash to work using the "good old" flex interface. I didn't find this script until digging further on the issue. However, is this by design/wanted? It seems that this option has been left out in the HTML5 version also in version 7.13.
Yeah it is by design. There are no plans to port security server management into the HTML5 console. That’s why I wrote the script to allow management of security servers with a GUI and to set the pairing password. Everyone should really be moving to UAG.
