title: How to check whether a user is in Administrator group in Install Shield 2009 Basic MSI Project
body: <p>Install Shield 2009, Premier, Basic MSI Projcet:[I want to allow only administrator users to run setup]
  In the 
  Releases->MyProductConfiguration->MyRelease->Setup.exe tab i chose "Required Execution Level" = "Invoker" and in 
  General Information->Product Properties I put a Install condition as Condition = "AdminUser" Message =  "Require Admin user to run this..."</p>
  
  <p>The problem is only the main Administrator can install it. Any other user say "Test" with Administrative privilege can't install and get the error message  "Require Admin user to run this..." </p>
  
  <p>So how to allow only those user who are in Admin group to install and restrict others.</p>
