title: MSI installer custom action identity problem
body: <p>I'm creating a custom action that executes a script on a database. The problem is that the connectios uses intergrated security, so when I try to open the connection i get the error: Login Failed for user 'Domain\ComputerName$'.</p>
  
  <p>When i check the identity on the custom action (using <code>System.Security.Principal.WindowsIdentity.GetCurrent()</code>) I always get "NT AUTHORITY\SYSTEM"
  but I'm running the installer under my account which has enough privileges on the Database.</p>
  
  <p>How can I run the custom action under the real user runnig the msi file or solve this problem in any other way? </p>
