wpf - Installing a program with setup.exe including multiple msi-files using C# process from a subfolder

Question

In my C# WPF application I want to install an other program. The other program consists of a setup.exe, multiple msi files and a vcredist.exe. I need to start the setup.exe because it hands over some parameters and information to the msi files and uses an update functionality for the existing version of the program. So I can't start the msi files directly.

programPath = programPath + @"setup.exe";
Process programsetup = Process.Start(programPath);
programsetup.WaitForExit();

Files are stored in root directory of my C# app. My problem is that I can't move the files to an subfolder because the msi files are always searched in the root directory and not in the subfolder.

now:

• ..myAppsetup.exe
• ..myAppclient.msi
• ..myApphost.msi
• ..myAppmanager.msi
• ..myAppvcredist.exe

My question: How can I move setup.exe and msi files in a subfolder and start it from there?

What I want:

• ..myAppoolkitsetup.exe
• ..myAppoolkitclient.msi
• ..myAppoolkithost.msi
• ..myAppoolkitmanager.msi
• ..myAppoolkitvcredist.exe

Error I get during setup when I do it this way: ..myAppclient.msi not found.

Answer 1

This code will directly launch setup.exe.

Properties -> right click Open to Resources.resx -> Top Left Add Existing File -> select the file.

byte[] resourceFile = Properties.Resources.setup;
        string destination = Path.Combine(Path.GetTempPath(), "setup.exe");
        System.IO.File.WriteAllBytes(destination, resourceFile);
        Process.Start(destination);
