I tried all of the suggestions but was still unable to run msiexec.exe
with parameters that contained spaces. So my solution ended up using System.Diagnostics.ProcessStartInfo
:
# can have spaces here, no problems
$settings = @{
CONNECTION_STRING = "... ..."
ENTITY_CONTEXT = "... ..."
URL = "..."
}
$settingsJoined = ($settings.Keys | % { "$_=""$($settings[$_])""" }) -join " "
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.WorkingDirectory = $ScriptDirectory
$pinfo.FileName = "msiexec.exe"
$pinfo.RedirectStandardError = $true
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$pinfo.Arguments = "/l* install.log /i installer.msi $settingsJoined"
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
$p.WaitForExit()
$stdout = $p.StandardOutput.ReadToEnd()
