Using InstallSoftwareRemotely.ps1 to upgrade VMware Horizon View Agent

I’ve had a lot of colleagues in the past ask me what I would use for smaller clients who did not have a software deployment tool such as SCCM to install or upgrade applications and the solution I typically present is the InstallSoftwareRemotely.ps1 PowerScript found here:

Install software on multiple computers remotely with PowerShell
https://gallery.technet.microsoft.com/scriptcenter/Install-software-on-9278d883

I’ve always used this script to perform small deployments and this blog post serves as a demonstration of how to use it.

Prerequisites for InstallSoftwareRemotely.ps1

The items that you’ll need to prepare as prerequisites before executing the command are as follows:

1. An administrator account on the target computers that you’ll be installing applications on (a domain admin would suffice)
2. Download Psexec.exe from https://docs.microsoft.com/en-us/sysinternals/downloads/psexec and place the executable C:WindowsSystem32 so the PS script could execute the command to enable PSRemoting
3. Place the software installation file, in this case the VMware Horizon View agent, into a network share accessible by the target computer and the account you will be running the PS script and ensure that it is not blocked (see one of my previous blog posts for more information about why this is important https://blog.terenceluk.com/2018/05/attempting-to-use-invoke-command.html)
4. Arguments (if reqiured) for the installation executable
5. A CSV file containing the computers that the software will be installed on (see the TechNet article’s description of the ComputerList for more information about the accepted sources)
6. Amount numeric value for the number of retries for the installation
7. The application name to check and see if it exists before installing the application (more information provided below)
8. The application version to check and see if it exists before installing the application (more information provided below)
9. Determine whether the target computer is 32-bit or 64-bit

There are several other switches available for the InstallSoftwareRemotely.ps1 but the ones mentioned above or the ones I typically use.  Please refer to the TechNet article for more information about the other ones available.

—————————————————————————————————————————–

Determining the application name and application version to check before installing

One of the things you can do with the InstallSoftwareRemotely.ps1 PS script is to have it check to see if the software you’re attempting to install already exists on the target computer.  The information required can be found via the following registry path:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall{IdentifyingNumber}

DisplayName

DisplayVersion

Here is an example of where the VMware Horizon View Agent 6.2.1.3284564 can be found:

Note that you can also use PowerShell to required information as described here:

Use PowerShell to Find and Uninstall Software
https://blogs.technet.microsoft.com/heyscriptingguy/2011/12/14/use-powershell-to-find-and-uninstall-software/

—————————————————————————————————————————-

Using a CSV for the target computers

Below is a screenshot of the format for a CSV file if you choose to use it as a list of the target computers:

Modification to the PS Script (for VMware Horizon View Agent only)

The slight modification I made to the PS script includes a restart command that executes when the installation of the application is completed.  The reason why chose to suppress the reboot with the switch that the VMware Horizon View Agent accepts is because allow the agent installer to restart the target computer would interrupt the InstallSoftwareRemotely.ps1 script before it completes thus causing errors to be thrown.  This should be applied to any applications that automatically restart upon completing its install.

Simply insert the Restart-Computer -ComputerName $Computer as shown in the screenshot below to achieve this:

The PowerShell script and required parameters

The following is the final PS script and its required parameters for the VMware Horizon View Agent install:

.InstallSoftwareRemotely.ps1 -AppPath ‘\fp09techSoftwareVMwareVMware Horizon ViewVMware Horizon View 6.2.1AgentVMware-viewagent-x86_64-6.2.1-3284564.exe’ -AppArgs ‘/S /V”/qn REBOOT=Reallysuppress’ -CSV ‘C:ScriptsVDIs.csv’ -Retries 2 -AppName ‘VMware Horizon View Agent’ -AppVersion ‘6.2.1.3284564’ -WMIQuery ‘select * from Win32_Processor where DeviceID=”CPU0″ and AddressWidth=”64″‘ -EnablePSRemoting -Credential

Note that the:

WMIQuery ‘select * from Win32_Processor where DeviceID=”CPU0″ and AddressWidth=”64″‘

… is to determine whether the target computer is a 32-bit or 64-bit Windows OS.  This is necessary because the agent we’re installing is for a 64-bit OS.

The resulting output of the script should look similar to the screenshot below:

Note that I am unable to determine what causes the error code 1641 during the VMware Horizon View Agent install even though it is a successful as this does not happen to other applications I’ve used this PS script with so be aware of the following:

• 1641 is success
• 1603 is failure

InstallSoftwareRemotely.ps1 Script with modification

Below is a copy and paste of the actual script I used for this demonstration.  Be advised that the script would likely receive updates and changes in the future.

<#

.SYNOPSIS

Install software remotely in a group of computers and retry the installation in case of error.

.DESCRIPTION

This script install software remotely in a group of computers and retry the installation in case of error.

It uses PowerShell to perform the installation. Target computer must allow Windows PowerShell Remoting.

Script can try to enable Windows PowerShell Remoting using Microsoft Sysinternals Psexec with the paramenter -EnablePSRemoting.

If PSExec is not found on computer, script asks to the user for download it and extract in system folder.

.PARAMETER AppPath

Path to the application executable, It can be a network or local path because entire folder will be copied to remote computer before installing and deleted after installation.

Example: ‘C:SoftwareTeamViewerTeamvieverHost.msi’ (Folder TeamViewer will be copied to remote computer before run ejecutable)

.PARAMETER AppArgs

Application arguments to perform silent installation.

Example: ‘/S /R settings.reg’

.PARAMETER LocalPath

Local path of the remote computer where copy application directory.

Default: ‘C:temp’

.PARAMETER Retries

Number of times to retry failed installations.

Default: 5

.PARAMETER TimeBetweenRetries

Seconds to wait before retrying failed installations.
