I have a Managed Bootstrapper Application written in Wix and I am having trouble handling reboots. So far I have an exe package with an exitcode
Also, In my Run Method I have
if (this.Command.Resume == ResumeType.Reboot)
{
model.SetWindowHandle(view);
this.Engine.Detect();
//view.Show();
Dispatcher.Run();
//this.Engine.Quit(model.FinalResult);
}
This is my ApplyComplete Event Handler
protected void ApplyComplete(object sender, ApplyCompleteEventArgs e)
{
this.model.FinalResult = e.Status;
if (model.bootstrapperApplication.Command.Action == LaunchAction.Uninstall)
{
model.bootstrapperApplication.Engine.Quit(0);
}
else
{
BootstrapperApplication.Dispatcher.BeginInvoke((Action)delegate ()
{
BootstrapperApplication.view.Close();
});
BootstrapperApplication.Dispatcher.InvokeShutdown();
e.Result = Result.Restart;
}
}
As of now, My bootstrapper installs the exe package and restarts the computer without showing any dialog box as to it being restarting. Also, After the computer restarts.. The managed bootstrapper does not launch by itself
How do I get the bootstrapper to launch after restarting?

My application (C#, VS2017) previously targeted Python 3.5.1. I have updated the system to Python 3.7.1 and have this is causing PythonEngine.Initialize() to crash the application without throwing an exception.
One internet suggestion was to set the Python env in VS, however this causes VS2017 to close when opening Python/environments. I switched to VS2019 and encountered the same issue with the stripped down code here:
using System.Windows.Forms;
using Python.Runtime;
namespace WindowsFormsApp3
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
try
{
PythonEngine.Initialize();
}
catch (Exception e)
{
string ex = e.ToString();
}
}
}
}
Python.Net was installed successfully using:
pip install pythonnet
UPDATE Dec 2022
There are 2 optional environment strings you can use to locate the python dll.
PYTHONNET_PYDLL explicitly set the dll name
PYTHONNET_PYVER explicitly set just the version string part of the dll name
Compiling with WINDOWS, OSX or LINUX defined is not required anymore
Here's my PythonNet init function.
Note that running "pip install pythonnet" only installs the ability to load & use CLR types & assemblies from Python. To embed PythonNet in a C# app, you actually don't need to install pythonnet on the Python side.
This function uses some globals set at startup.
Program.PythonHome -- points to the Python root folder I'm using
Program.ScriptsDir -- my own app python scripts dir
Program.ApplicationName -- just my own app name
I also call PythonEngine.BeginAllowThreads(); as I'm calling from multiple threads.
public static void InitPython(Microsoft.Extensions.Logging.ILogger logger)
{
string py_home = Program.PythonHome;
string py_path = $"{py_home};";
// will be different on linux/mac
string[] py_paths = {"DLLs", "lib", "lib/site-packages", "lib/site-packages/win32"
, "lib/site-packages/win32/lib", "lib/site-packages/Pythonwin" };
foreach (string p in py_paths)
{
py_path += $"{py_home}/{p};";
}
try
{
PythonEngine.PythonPath = $"{Program.ScriptsDir};{py_path}";
PythonEngine.PythonHome = Program.PythonHome;
PythonEngine.ProgramName = Program.ApplicationName;
PythonEngine.Initialize();
PythonEngine.BeginAllowThreads();
logger.LogInformation("Python Version: {v}, {dll}", PythonEngine.Version.Trim(), Runtime.PythonDLL);
logger.LogInformation("Python Home: {home}", PythonEngine.PythonHome);
logger.LogInformation("Python Path: {path}", PythonEngine.PythonPath);
}
catch (System.TypeInitializationException e)
{
throw new Exception($"FATAL, Unable to load Python, dll={Runtime.PythonDLL}", e);
}
catch (Exception e)
{
throw new Exception($"Python initialization Exception, {e.Message}", e);
}
}
How is this behavior set? I can't find how to disable the bootstrapper from booting on reboot. I will install the program, turn off the computer and on the next day, when I start the computer, the bootstrapper window appears. Even though it will uninstall the bootstrapper. And when I installed it several times in tests, it happens that later I have several windows. But this pop-up doesn't always happen, and I don't know what it depends on.
Edit
Looking at the logs after the RegisterBegin:
Session begin, registration key:
SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{bf97c7e8-2ef4-4439-9504-96a7736c10f4},
options: 0x4, disable resume: No Registering bundle dependency
provider: {bf97c7e8-2ef4-4439-9504-96a7736c10f4}, version: 1.0.120.0
Updating session, registration key:
SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{bf97c7e8-2ef4-4439-9504-96a7736c10f4},
resume: Active, restart initiated: No, disable resume: No
You see disable resume: No, I can't find anything about it, but maybe it causes the application to run after reboot.
Edit2
It happen because bootstrapper add register HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\RunOnce.
But can't find how turn off it.
Ultimately, the reason for this was adding the RunOnce registry for the bootstrapper. It is written on the Internet that, according to the developers, this is a confirmation of the success of the installation. But in my case, it is unnecessary for me, because I do the post-configuration test myself. To prevent this, I hooked up to the OnRegisterComplete event and remove all registers containing the name of my installer.
However, this requires running the bootstrapper with administrative privileges.
private void OnRegisterComplete(object sender, RegisterCompleteEventArgs e)
{
try
{
string registryKey = #"SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\RunOnce";
RegistryKey key32 = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32);
RegistryKey key = key32.OpenSubKey(registryKey, true);
if (key != null)
{
var names = key.GetValueNames();
for (int i = 0; i < names.Length; i++)
{
var value = key.GetValue(names[i]);
if (value.ToString().Contains("NameInstaller.exe"))
key.DeleteValue(names[i]);
}
key.Close();
}
}
catch (Exception ex)
{
}
}
Once my program is installed on a client machine, how do I force my program to run as an administrator on Windows 7?
You'll want to modify the manifest that gets embedded in the program. This works on Visual Studio 2008 and higher: Project + Add New Item, select "Application Manifest File". Change the <requestedExecutionLevel> element to:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
The user gets the UAC prompt when they start the program. Use wisely; their patience can wear out quickly.
Adding a requestedExecutionLevel element to your manifest is only half the battle; you have to remember that UAC can be turned off. If it is, you have to perform the check the old school way and put up an error dialog if the user is not administrator (call IsInRole(WindowsBuiltInRole.Administrator) on your thread's CurrentPrincipal).
The detailed steps are as follow.
Add application manifest file to project
Change application setting to "app.manifest"
Update tag of "requestedExecutionLevel" to requireAdministrator.
Note that using this code you need to turn off the security settings of ClickOnce, for do this, go inside Properties -> Security -> ClickOnce Security
I implemented some code to do it manually:
using System.Security.Principal;
public bool IsUserAdministrator()
{
bool isAdmin;
try
{
WindowsIdentity user = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(user);
isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
}
catch (UnauthorizedAccessException ex)
{
isAdmin = false;
}
catch (Exception ex)
{
isAdmin = false;
}
return isAdmin;
}
You can embed a manifest file in the EXE file, which will cause Windows (7 or higher) to always run the program as an administrator.
You can find more details in Step 6: Create and Embed an Application Manifest (UAC) (MSDN).
While working on Visual Studio 2008, right click on Project -> Add New Item and then chose Application Manifest File.
In the manifest file, you will find the tag requestedExecutionLevel, and you may set the level to three values:
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
OR
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
OR
<requestedExecutionLevel level="highestAvailable" uiAccess="false" />
To set your application to run as administrator, you have to chose the middle one.
Another way of doing this, in code only, is to detect if the process is running as admin like in the answer by #NG.. And then open the application again and close the current one.
I use this code when an application only needs admin privileges when run under certain conditions, such as when installing itself as a service. So it doesn't need to run as admin all the time like the other answers force it too.
Note in the below code NeedsToRunAsAdmin is a method that detects if under current conditions admin privileges are required. If this returns false the code will not elevate itself. This is a major advantage of this approach over the others.
Although this code has the advantages stated above, it does need to re-launch itself as a new process which isn't always what you want.
private static void Main(string[] args)
{
if (NeedsToRunAsAdmin() && !IsRunAsAdmin())
{
ProcessStartInfo proc = new ProcessStartInfo();
proc.UseShellExecute = true;
proc.WorkingDirectory = Environment.CurrentDirectory;
proc.FileName = Assembly.GetEntryAssembly().CodeBase;
foreach (string arg in args)
{
proc.Arguments += String.Format("\"{0}\" ", arg);
}
proc.Verb = "runas";
try
{
Process.Start(proc);
}
catch
{
Console.WriteLine("This application requires elevated credentials in order to operate correctly!");
}
}
else
{
//Normal program logic...
}
}
private static bool IsRunAsAdmin()
{
WindowsIdentity id = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(id);
return principal.IsInRole(WindowsBuiltInRole.Administrator);
}
As per
<requestedExecutionLevel level="highestAvailable" uiAccess="false" />
you will want to add an application manifest if you don't already have one or don't know how to add one. As some projects don't automatically add a separate manifest file, first go to project properties, navigate to the Application tab and check to make sure your project is not excluding the manifest at the bottom of the tap.
Next, right click project
Add new Item
Last, find and click Application Manifest File
In Visual Studio 2010 right click your project name.
Hit "View Windows Settings", this generates and opens a file called "app.manifest".
Within this file replace "asInvoker" with "requireAdministrator" as explained in the commented sections within the file.
You can create the manifest using ClickOnce Security Settings, and then disable it:
Right click on the Project -> Properties -> Security -> Enable ClickOnce Security Settings
After you clicked it, a file will be created under the Project's properties folder called app.manifest once this is created, you can uncheck the Enable ClickOnce Security Settings option
Open that file and change this line :
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
to:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
This will make the program require administrator privileges.
In case you want a code-only solution for some reason, here's a standalone class file. Just call "AdminRelauncher.RelaunchIfNotAdmin()" at application start:
using System;
using System.Diagnostics;
using System.Reflection;
using System.Security.Principal;
public static class AdminRelauncher
{
public static void RelaunchIfNotAdmin()
{
if (!RunningAsAdmin())
{
Console.WriteLine("Running as admin required!");
ProcessStartInfo proc = new ProcessStartInfo();
proc.UseShellExecute = true;
proc.WorkingDirectory = Environment.CurrentDirectory;
proc.FileName = Assembly.GetEntryAssembly().CodeBase;
proc.Verb = "runas";
try
{
Process.Start(proc);
Environment.Exit(0);
}
catch (Exception ex)
{
Console.WriteLine("This program must be run as an administrator! \n\n" + ex.ToString());
Environment.Exit(0);
}
}
}
private static bool RunningAsAdmin()
{
WindowsIdentity id = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(id);
return principal.IsInRole(WindowsBuiltInRole.Administrator);
}
}
THIS DOES NOT FORCE APPLICATION TO WORK AS ADMINISTRATOR.
This is a simplified version of the this answer, above by #NG
public bool IsUserAdministrator()
{
try
{
WindowsIdentity user = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(user);
return principal.IsInRole(WindowsBuiltInRole.Administrator);
}
catch
{
return false;
}
}

Hi I have these two binary files:
<Binary Id="Sentinel" SourceFile="sentinel_setup.exe"/>
<Binary Id="Hasp" SourceFile="HASPUserSetup.exe"/>
And I would like to start them on a button click like so:
<CustomAction Id="LaunchHasp" BinaryKey="Hasp" ExeCommand="" Return="asyncWait" />
<CustomAction Id="LaunchSentinel" BinaryKey="Sentinel" ExeCommand="" Return="asyncWait"/>
<Publish Event="DoAction" Value="LaunchHasp">1</Publish>
But it doesn't work, It only works when I run the installer from the command line with elevated privileges. What am I doing wrong? Thanks
Or can someone tell me how I could extract the file from the binary table using a c++ custom action as I cannot get it working at all..:(
Immediate custom actions doesn't have elevated privileges. You should use deffered custom actions for such needs. Any action that make changes to the destimation environment should be deffered. For more details read this article: http://bonemanblog.blogspot.com/2005/10/custom-action-tutorial-part-i-custom.html
<CustomAction Id="LaunchHasp" Impersonate="no" Execute="deferred" BinaryKey="Hasp" ExeCommand="" Return="asyncWait" />
Though deffered custom actions are executed during installation phase, not on button click. Revise your installer logic. As I understand, your exe file "sentinel_setup.exe" changes the system, so should be scheduled between InstallInitialize and InstallFinalize events in InstallExecuteSequence
I would recommend adding a checkbox, that user should mark to install your "Hasp" (or installer Feature which user should select in the feature tree). And add deffered custom action with condition on this checkbox state.
Sometimes it is really required to launch admin actions during or before installer UI sequence. In this case you need to create a setup bootstrapper which asks for permission elevation and does required actions before running MSI process. To ask for permissions you need to add application manifest to your bootstrapper project. My bootstrapper is quite simple, but works in many cases. It is Windows application (though without any Windows forms - it allows to hide console window) which contains only icon, application manifest and small code file:
using System;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace SetupBootstrapper
{
class Program
{
[STAThread]
static void Main(string[] args)
{
var currentDir = AppDomain.CurrentDomain.BaseDirectory;
var parameters = string.Empty;
if (args.Length > 0)
{
var sb = new StringBuilder();
foreach (var arg in args)
{
if (arg != "/i" && arg != "/x" && arg != "/u")
{
sb.Append(" ");
sb.Append(arg);
}
}
parameters = sb.ToString();
}
bool isUninstall = args.Contains("/x") || args.Contains("/u");
string msiPath = Path.Combine(currentDir, "MyMsiName.msi");
if(!File.Exists(msiPath))
{
MessageBox.Show(string.Format("File '{0}' doesn't exist", msiPath), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
return;
}
string installerParameters = (isUninstall ? "/x" : "/i ") + "\"" + msiPath + "\"" + parameters;
var installerProcess = new Process { StartInfo = new ProcessStartInfo("msiexec", installerParameters) { Verb = "runas" } };
installerProcess.Start();
installerProcess.WaitForExit();
}
}
}
