Enable Adobe Flash support for the VMware Horizon Administrator console

Adobe Flash is no longer supported after December 31, 2020, and currently disabled by default.

During my consulting work, I still see organizations that use Adobe Flash-based applications such as the VMware Horizon Administrator. VMware Horizon 7.10 has an HTML5 based Horizon Console that nearly feature-complete and replaces the Adobe Flash-based Horizon Console.

For organizations, it can difficult to manage there VMware Horizon environments below version 7.10 of VMware Horizon. This can be done by enabling Adobe Flash temporarily. Caution: Enabling Adobe Flash is a security breach for your environment. So use with caution!!!

With the following steps you can enable Adobe Flash support on a Windows:

  • Download Firefox 78.6.1 ESR, link
  • Create or edit the following file: ‘C:\Windows\SysWOW64\Macromed\Flash\mms.cfg’ with the following settings:
EOLUninstallDisable=1
SilentAutoUpdateEnable=0
EnableAllowList=1
AutoUpdateDisable=1
ErrorReportingEnable=1
AllowListUrlPattern=https://fqdn-of-the-horizon-connection-server:443
  • Replace the ‘AllowListURLPattern’ with the FQDN of the VMware Horizon Connection server or load balancer URL
  • Open Firefox and enter the VMware Horizon Connection server or load balancing URL

When you are still using the VMware Horizon Administrator make sure to upgrade your VMware Horizon environment. The end of general support for Horizon 7 is March 2021. Upgrade to minimal VMware 7.13 (has general support till October of 2022) or VMware Horizon 8.x.

Patch a vCenter Server High Availability (VCHA) environment

Last week I tried to patch a vCenter Server High Availability (VCHA) 7 cluster environment. I read the documentation and the procedure described looks still the same as in version 6.x. First patch the witness node, then the passive node, failover the active node, and patch the passive node using the software-packages tool. The whole process is described in this link.

When I tried to stage the ISO on the witness node the following error occurred:

You can not patch a vCenter Server appliance in a vCenter HA cluster. resolution: You must remove the vCenter HA configuration, apply patches to vCenter Server appliance, and then reconfigure your vCenter HA deployment.

So I removed the vCenter Server HA cluster configuration and patched the single vCenter Server Appliance.

After the patching of the single VCSA, I redeployed the VCHA cluster again.

Conclusion: The vCenter Server HA cluster documentation still has the VCHA 6 update procedure documented that does not work anymore. I will update this blog article if there is more information available.
