title: Runtime variables passed through to packaged installers?
body: <p>I've got an NSIS script that checks the platform it's running on and launches an appropriate MSI. This works great, but it means that I can't use parameters like <code>/SILENT</code> on my bundled installers. </p>
  
  <p>Is there any way to get the whole parameter string and pass it on the the msi installers?</p>
  
  <p>Here's my code at the moment:</p>
  
  <pre><code>Section
  Initpluginsdir
  ${If} ${RunningX64}
    File "/oname=$pluginsdir\inst.msi" "${DIR}\64bit.msi"
  ${Else}
    File "/oname=$pluginsdir\inst.msi" "${DIR}\32bit.msi"
  ${EndIf}
  ExecWait '"msiexec" /i "$pluginsdir\inst.msi"'
  SectionEnd
  </code></pre>
