Calling script in elevated mode with more than one named argument - powershell

Question

Test.ps1
Param (
[String]$CountryCode,
[String]$FilesPath,
[String]$KeepassDatabase,
[String]$KeepassKeyFile,
[String]$EventLog,
[String]$EventSource
)
Write-Host 'Ok' -ForegroundColor Yellow
Write-Host $PSBoundParameters
Start-Sleep -Seconds 5
The goal is to call the script with named parameters in elevated mode. When using named parameters without $Credential, it works fine. The window pops up and the word Ok is displayed:
$StartParams = #{
ArgumentList = "-File `"Test.ps1`" -verb `"runas`" -FilesPath `"S:\Files`" -CountryCode `"XXX`""
}
Start-Process powershell #StartParams
When I add the Credential argument it also pops-up but I can't see anything:
$StartParams = #{
Credential = Get-Credential
ArgumentList = "-File `"Test.ps1`" -verb `"runas`" -FilesPath `"S:\Files`" -CountryCode `"XXX`""
}
Start-Process powershell #StartParams
Am I missing something super obvious here? Even when using the same credentials as the logged on user, I can't see the text.

You need to specify an absolute path to the file. The new PowerShell-process (which will run as admin) doesn't run in the same working directory as your current session.
Try:
$StartParams = #{
FilePath = "powershell.exe"
Credential = Get-Credential
Verb = "RunAs"
ArgumentList = "-File `"c:\temp\Test.ps1`" -FilesPath `"S:\Files`" -CountryCode `"XXX`""
}
Start-Process #StartParams
If you only know the relative path, use Resolve-Path to convert it. Ex:
ArgumentList = "-NoExit -File `"$(Resolve-Path test.ps1 | Select-Object -ExpandProperty Path)`" -FilesPath `"S:\Files`" -CountryCode `"XXX`""
You should also look into string format or here-string so you can avoid escaping every double quote. It makes your life easier:
#Using here-string (no need to escape double quotes)
ArgumentList = #"
-NoExit -File "$(Resolve-Path test.ps1 | Select-Object -ExpandProperty Path)" -FilesPath "S:\Files" -CountryCode "XXX"
"#
#Using string format
ArgumentList = '-NoExit -File "{0}" -FilesPath "{1}" -CountryCode "{2}"' -f (Resolve-Path test.ps1 | Select-Object -ExpandProperty Path), "S:\Files", "XXX"
