title: Advanced installer powershell script set property
body: <p>I am using advanced installer 10.7.1. I am adding the custom action of 'run windows powershell script'. What this script does is to check if the installer is being run on an azure vm or not. if it is, only then does it allow the user to install. The script runs fine on the vm, I've checked it. but now I need to display an error message on the basis of a script's result. which means I have to set some property in the script, on the basis of which I will display the error message.
  can anybody tell me how to set advanced installer's property through a powershell script.</p>
