I am trying to upgrade some software using PowerShell and I am not sure if my parameters are correctly formatted . See highlighted text
# Silent Install Secure Secure Authentication
# http://repository.eset.com/v1/com/eset/apps/business/esa/windows/v2/2.7.32.0/esa_nt64_enu.msi
# Path for the workdir
$workdir = "c:\scripts\"
# Check if work directory exists if not create it
If (Test-Path -Path $workdir -PathType Container)
{ Write-Host "$workdir already exists" -ForegroundColor Red}
ELSE
{ New-Item -Path $workdir -ItemType directory }
# Download the installer
$source = "http://repository.eset.com/v1/com/eset/apps/business/esa/windows/v2/2.7.32.0/esa_nt64_enu.msi"
$destination = "$workdir\esa_nt64_enu_v2.msi"
# Check if Invoke-Webrequest exists otherwise execute WebClient
if (Get-Command 'Invoke-Webrequest')
{
Invoke-WebRequest $source -OutFile $destination
}
else
{
$WebClient = New-Object System.Net.WebClient
$webclient.DownloadFile($source, $destination)
}
Invoke-WebRequest $source -OutFile $destination
# Start the installation
msiexec.exe /i "$workdir\esa_nt64_enu_v2.msi" ADDLOCAL="Credential_Provider" /qb /L*v "c:\esa_install_log.txt"
# Wait XX Seconds for the installation to finish
Start-Sleep -s 35
# Remove the installer
rm -Force $workdir\esa_nt64*
