Uninstalling Omnissa Horizon 8 Components Silently by Using MSI Command-Line Options

You can uninstall Horizon 8 components by using Microsoft Windows Installer (MSI) command-line options.

Syntax

        msiexec.exe
        /qb
        /x
        product_code
      

Options

The /qb option displays the uninstall progress bar. To suppress displaying the uninstall progress bar, replace the /qb option with the /qn option.

The /x option uninstalls the Horizon 8 component.

The product_code string identifies the Horizon 8 component product files to the MSI uninstaller. You can find the product_code string by searching for ProductCode in the %TEMP%\vmmsi.log file that is created during the installation.

For information about MSI command-line options, see Microsoft Windows Installer Command-Line Options.

Uninstall a Horizon Agent Example

To uninstall a 32-bit Horizon Agent, enter the following command:

msiexec.exe /qb /x {B23352D8-AD44-4379-A56E-0E337F9C4036}

To uninstall a 64-bit Horizon Agent, enter the following command:

msiexec.exe /qb /x {53D6EE37-6B10-4963-81B1-8E2972A1DA4D}

Add a verbose log to the command.

/l*v "%TEMP%\vmmsi_uninstall.log"

If you do not explicitly pass the /loption, the default verbose log file is %TEMP%\MSInnnn.log, where nnnn is a four-character GUID.

The Horizon Agent uninstallation process retains some registry keys. These keys are required for retaining the Omnissa Horizon Connection Server configuration information that enables the remote desktop to continue being paired with the Horizon Connection Server even if the agent is uninstalled and then reinstalled. Removing these registry keys will break that pairing.

The following table lists the registry keys that are retained in relation to different deployment environments. If a registry key is not marked under an environment column, it is not applicable to that environment.
