title: ProgramFilesFolder Set to C:\ when using /a switch for msiexec
body: <p>I have an .MSI installer that I created using WIX and works fine when opening the file from windows explorer or installing from a command window using msiexec /i. The problem is that I need to use /a to install it using a group policy when the computer turns on.</p>
  
  <p>When using the /i option the ProgramFilesFolder value is set correctly to "C:\Program Files (x86)\".</p>
  
  <p>When using the /a option the value of ProgramFilesFolder is set to "C:\", and then I get an error (on the Log) that says:</p>
  
  <p><code>The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2203. The arguments are: C:\Referrals.msi, -2147287035,</code></p>
  
  <p>Note: I am <strong>not</strong> running the .MSI file from "C:\"</p>
