Horizon Install Order and Silent Installs

This blog post is regarding the correct order of installing/Uninstalling Horizon Agents, Silent Installs/Uninstalls, and enabling FIPS.


VMware Horizon Install Sequence Order 



Installation of various user experience, environment and VDI agents can cause unexpected issues of fail completely if installed in the incorrect order.
If you need to upgrade the Horizon View Agent you will need to reverse this process from the bottom-up.


1.     Hypervisor Tools


2.     VDI Agent


3.     VMware vRealize Operations Manager Agent

  • If you have a View 5.0 or 5.1 environment, you must manually install the desktop agent on your desktops. The vROPs Agent is included with the Horizon View agent 5.2 or later.


4.     VMware vRealize Log Insight Agent

  • If Log Insight is not deployed in the environment, skip this step.


4.     VMware User Environment Manager (UEM) Agent (formerly Immidio Flex+)

  • If VMware UEM is not deployed in the environment, skip this step.


5.     VMware App Volumes Agent

  • If VMware App Volumes is not deployed in the environment, skip this step.

VMware vRealize Log Insight Manager, Silent Install Instructions:


  1. Log in to the Windows machine on which to install or update the vRealize Log Insight Windows agent.

  4. Run the following command to install or update with default values. Replace Version-Build_Number with your version and build number.

The /quiet option runs the command silently, and the /lxv option creates a log file in the current directory.

(Optional) : Specify a user service account for the vRealize Log Insight Windows agent service to run under.

  1. Open a Windows command prompt on your machine.
  2. Type the following command to upgrade the agent:

msiexec.exe /i “App Volumes Agent.msi” /qn REINSTALLMODE=vomus REINSTALL=ALL


Disabling EnforceSSLCertificateValidation with REGKEY

















You can disable SSL certificate validation after you have installed the App Volumes agent. To do this manually make the modification to registry to create your own .reg file to import. You will need to disable EnforceSSLCertificateValidation if you have FIPS enabled in your environment.

Registry location, set value to ‘00000000’ to disable:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\svservice\Parameters] “EnforceSSLCertificateValidation”=dword:00000000


Registry file import command: regedit.exe /s path of .reg file


Example of importing a registry file:


reg import c:\location\regfile.reg



Rarely needed, unless your organization has a hard security requirement, you may need to enable FIPS mode. Please keep in mind, enabling FIPS mode, can break a lot of things if not properly setup. You can Enable or disable the FIPS setting via a registry setting, GPO, or Local Policy. To check whether FIPS is enabled or disabled in the registry, follow the following steps:

  1. Press Windows Key+R to open the Run dialog.
  2. Type “regedit” into the Run dialog box (without the quotes) and press Enter.
  3. Navigate to “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy\”.
  4. Look at the “Enabled” value in the right pane.
  5. If it’s set to “0”, FIPS mode is disabled. If it’s set to “1”, FIPS mode is enabled.
  6. To change the setting, double-click the “Enabled” value and set it to either “0” or “1”.
  7. Restart the computer.

FIPS mode needs to be enable on the Windows servers and on the golden image.
