Install or Uninstall a Horizon Agent Patch Silently

You can use the silent installation feature of the Microsoft Windows Installer (MSI) to install and uninstall a Horizon Agent patch. In a silent installation, you use the command line and do not have to respond to wizard prompts.

Prerequisites

• Verify that you have administrative rights on the virtual machine or physical PC.

• Select the product version and download the Horizon Agent Update Patch installer file from the Horizon product page in Customer Connect.

  The installer filename is -Horizon-Agent-x86_64-YYMM-y.y.y-xxxxxx.exe, where YYMM is the marketing version number, y.y.y is the internal version number, and xxxxxx is the build number.

Procedure

1. Open a Windows command prompt as administrator on the virtual machine or physical PC.

2. To install a Horizon Agent patch where Horizon Agent is installed, run the .exe file: msiexec /p -Horizon-Agent-x86_64-YYMM-y.y.y-xxxxxx.exe /qn REINSTALL=ALL”

   After installing the patch, verify the patch build number is updated in the registry.

3. To uninstall a Horizon Agent patch where Horizon Agent is installed, run a PowerShell script: remove-patch.ps1

   ProductCode-driven command line example: msiexec /package {product_code} /uninstall {patch_guid} /passive

   After uninstalling the patch, check the registry to make sure that no reference of the patch exists. Verify the services are in the same state as they were before uninstalling the patch.
