Hi!

Trying to install or upgrade cygwin silently. Calling a newly downloaded 
setup-x86_64.exe (Power Shell-snipplets):

$URL = "https://www.cygwin.com/setup-x86_64.exe"
$dlp = "C:\INSTALL\Apps\c\cygwin"
$nsf = "$dlp\setup-x86_64.new"
$isf = "$dlp\setup-x86_64.exe"
$isl = "$dlp\setup-x86_64.log"
$ise = "$dlp\setup-x86_64.err"
$cll = "$dlp\setup-x86_64.cll"

$ProgressPreference = 'SilentlyContinue'
Invoke-WebRequest -Uri $URL -OutFile $nsf

$ProgressPreference = 'Continue'
if (Test-Path -Path $isf -PathType Leaf) {
     Remove-Item -Path $isf
}
Rename-Item -Path $nsf -NewName $isf

$SetupOpts = @{
     FilePath = $isf
     ArgumentList = @(
         "--verbose",
         "--delete-orphans",
         "--upgrade-also",
         "--quiet-mode",
         "--wait",
         "--no-desktop",
         "--local-package-dir", "`"$localDir`"",
         "--proxy", "`"<proxy>:8080`"",
         "--root", "`"C:\cygwin`""
     )
     WindowStyle = "Hidden"
     PassThru = $True
     Wait = $True
     RedirectStandardOutput = "$isl"
     RedirectStandardError = "$ise"
}
$proc = Start-Process @SetupOpts

Setup starts, but then does nothing. It does create the logs, but they 
do not contain anything. They stay empty. Anything missing from the options?

Calling the power shell script from an elevated prompt directly seems to 
work as expected. It bails out if it is not an elevated prompt. Calling 
it remotely it hangs and nothing happens. Any idea? Any hint?
