[wix-users] Run as Administrator

[Hoover, Jacob]

Please note, running your BA elevated is against best practices and it may result in fallout which won't be supported.  You should really ask yourself why you think your BA needs to run elevated, as 99.99% of the time the reasons are invalid.  Your BA should never modify machine state, that's the engine/installers job, and that is what WiX has been designed to do.

Below is the code which will help you in creating a Self-Elevating MSI

Step 1 Create a custom action in your MSI project, Say - [ElevateInstallerCA]

public static ActionResult ElevateInstaller(Session session) {
   WindowsPrincipal principal = new
WindowsPrincipal(WindowsIdentity.GetCurrent());
   bool hasAdministrativeRight =
principal.IsInRole(WindowsBuiltInRole.Administrator);
   if (!hasAdministrativeRight)
   {
       try
       {
           ProcessStartInfo processInfo = new ProcessStartInfo();
           processInfo.Verb = "runas";
   processInfo.FileName = "msiexec";
                    processInfo.Arguments = "/i \"" + session["OriginalDatabase"] + "\"";

           using (Process wrapperProcess = Process.Start(processInfo))
           {
               wrapperProcess.WaitForExit();
           }
           session["ElevatedFromCA"] = "1";
           return ActionResult.SkipRemainingActions;
       }
       catch
       {
           //Exit Gracefully, Probably the user canceled the UAC window
           return ActionResult.UserExit;
       }
   }
   else
   {
        return ActionResult.Success;
   }
}

In your wix project where you have defined your custom actions define this custom action:

<Binary Id="ElevateInstallerBin"
SourceFile="..\ElevateInstaller\bin\Release\ElevateInstallerCustomAction.CA.dll"
/>
<CustomAction Id="ElevateInstallerCA" BinaryKey="ElevateInstallerBin"
DllEntry="ElevateInstaller" Execute="immediate" Return="check" />

Change the InstallUISequence such that this custom action is run the first when the MSI begins execution

<InstallUISequence>
     <Custom Action="ElevateInstallerCA"
Before="FindRelatedProducts"></Custom>
</InstallUISequence>

Hope this helps,

Let me know if you have any questions on this.

Kaveesh
