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.
I noticed that there is one issue (possibly a bug), but it's been in the HTML client since the first version, and I'm on 7.13. If I rename a snapshot in vCenter, and Horizon is currently using that snapshot as the default image in a pool, Horizon will not allow me to change the snapshot. I just get a blank box under "Parent Image" and the browse button doesn't do anything.
When I had this happen before, I had to launch the Flex console, edit the pool and click vcenter settings tab. Then it pops up an error message saying "Error occurred during vcenter operation". But once I click OK on that error, I'm able to select a different snapshot, and I can go back to the HTML console and it's back to normal.
