title: Powershell Throws “Cannot Validate The Argument on Parameter” Error But Still Works?
body: <p>Fairly simple line in my Powershell script to run an install. The line works- the installer comes up and completed successfully. Yet this error persists.</p>
  <pre><code>Start-Process -Wait (msiexec.exe /I “C:\Temp\MBAM 2.5\Installers\x64\MBAMClient.msi”)
  </code></pre>
  <p>The error:</p>
  <pre><code>Start-Process : A positional parameter cannot be found that accepts argument ‘C:\Temp\MBAM 2.5\Installers\x64\MBAMClient.msi’
  At line:1 char:1
  </code></pre>
  <p>Even though it works it’s important not to have errors in my console not only for obvious reasons but also for approval.</p>
