使用子文件夹中的 C# 进程安装包含多个 msi 文件的 setup.exe 程序

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:

• ..\myApp\setup.exe
• ..\myApp\client.msi
• ..\myApp\host.msi
• ..\myApp\manager.msi
• ..\myApp\vcredist.exe

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

What I want:

• ..\myApp\toolkit\setup.exe
• ..\myApp\toolkit\client.msi
• ..\myApp\toolkit\host.msi
• ..\myApp\toolkit\manager.msi
• ..\myApp\toolkit\vcredist.exe

Error I get during setup when I do it this way: ..\myApp\client.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);

I've solved it with ProcessStartInfo.WorkingDirectory .

Problem/Solution: If you start a setup file with Process which loads during installation some msi files from same directory you need to set WorkingDirectory .

Code example:

string ToolkitExe = myAppPath + @"\myApp\toolkit\setup.exe";
string ToolkitPath = myAppPath + @"\myApp\toolkit\";
ProcessStartInfo startInfo = new ProcessStartInfo(myAppPath + @"\myApp\toolkit\");
startInfo.WorkingDirectory = myAppPath;
Process p = Process.Start(startInfo);
p.WaitForExit();
RunAll();
