I use PSAppDeployToolkit for mine. Here's the installation part of the code:

    ##*===============================================
        ##* PRE-INSTALLATION
        ##*===============================================
        [String]$installPhase = 'Pre-Installation'

        ## Show Welcome Message, close Internet Explorer if required, allow up to 3 deferrals, verify there is enough disk space to complete the install, and persist the prompt
        Show-InstallationWelcome -CloseApps 'lf,outlook,winword,excel,powerpnt,Laserfiche.OfficeMonitor,Laserfiche Webtools Agent' -AllowDefer -DeferTimes 3 -CheckDiskSpace -PersistPrompt

        ## Show Progress Message (with the default message)
        Show-InstallationProgress

        ## <Perform Pre-Installation tasks here>
        # Uninstall Laserfiche client applications first
        $detPackage = Get-Package -Name 'Laserfiche*' -ProviderName msi  -ErrorAction SilentlyContinue | Where-Object {$_.Name -match 'Laserfiche Office Integration.+'}
        If ($detPackage) { $detPackage | Uninstall-Package }

        ##*===============================================
        ##* INSTALLATION
        ##*===============================================
        [String]$installPhase = 'Installation'

        ## Handle Zero-Config MSI Installations
        If ($useDefaultMsi) {
            [Hashtable]$ExecuteDefaultMSISplat = @{ Action = 'Install'; Path = $defaultMsiFile }; If ($defaultMstFile) {
                $ExecuteDefaultMSISplat.Add('Transform', $defaultMstFile)
            }
            Execute-MSI @ExecuteDefaultMSISplat; If ($defaultMspFiles) {
                $defaultMspFiles | ForEach-Object { Execute-MSI -Action 'Patch' -Path $_ }
            }
        }

        ## <Perform Installation tasks here>
        $MsiPath = Get-ChildItem -Path "$dirFiles\ClientWeb" -Include lfoffice-x64_en.msi -File -Recurse -ErrorAction SilentlyContinue
        If($MsiPath.Exists) {
            Write-Log -Message "Found $($MsiPath.FullName), now attempting to install $installTitle."
            Execute-MSI -Action Install -Path "$MsiPath" -Parameters '/QN' -AddParameters "ACCEPT_EULA=YES"
        }

Cary, the LF Office Integration is part of the Windows Installer. If you look at the Unattended documentation that Craig linked to, it will show you that there are different levels that can be used to install the components you are wanting.

If you don't have SSCM you can create a batch file that can be pushed out as part of a Group Policy to do the install.

Thanks for the reply. 

For some reason, I am missing the Laserfiche Deployment Toolkit Configuration Utility.exe after I extract it.

Hi Cary! The latest LF Office Integrations installer can also be found here
