2. Open PowerShell ISE as Administrator
3. Paste the script into the white window
4. Click the green run button, or press the F5 key

```powershell
param(
    [switch]$Force,
    [string]$DownloadPath = "$env:TEMP\ComputleAudio"
)

Write-Host "Computle Workstation TGX Microphone Redirection Setup" -ForegroundColor Green

if (-NOT ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) {
    Write-Error "This script must be run as Administrator."
    exit 1
}

$downloadUrl = "https://downloads.oncomputle.com/virtual-audio-driver.exe"
$exeFile = "$DownloadPath\virtual-audio-driver.exe"

if (!(Test-Path $DownloadPath)) {
    New-Item -ItemType Directory -Path $DownloadPath -Force | Out-Null
}

Invoke-WebRequest -Uri $downloadUrl -OutFile $exeFile -UseBasicParsing

$installProcess = Start-Process -FilePath $exeFile -ArgumentList "/S" -Wait -PassThru

if ($installProcess.ExitCode -ne 0 -and $installProcess.ExitCode -ne 3010) {
    Write-Error "Installation failed on this Computle workstation with exit code: $($installProcess.ExitCode)"
    exit 1
}

Remove-Item $DownloadPath -Recurse -Force

if (!$Force) {
    Write-Host "Computle workstation microphone redirection setup completed successfully!" -ForegroundColor Green
    $reboot = Read-Host "Restart computer? (y/n)"
    if ($reboot -eq 'y' -or $reboot -eq 'Y') {
        Restart-Computer -Force
    }
}
```
