[wix-users] Run as Administrator

[Kaveesh Dashora]

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
