检查是否安装了软件，如果没有，请使用c＃安装

Question

I've finished my C# WPF application, but I have a little problem :

My WPF application must need Adobe flash and .net framework and few softwares to run properly.
so this application have to install these softwares one by one automatically if not installed in client system instead of install by user self.

i have idea about check using "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall" but dont know how to complete?

string uninstallKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
            RegistryKey rk = Registry.LocalMachine.OpenSubKey(uninstallKey);
            {
                foreach (string skName in rk.GetSubKeyNames())
                {
                    RegistryKey sk = rk.OpenSubKey(skName);
                    {
                        if (sk.GetValue("DisplayName") == "Adobe Flash Player ActiveX")
                        {
                            MessageBox.Show("Installed");

                           // how to run the software one by one here???????

                        }

                    }
                }
            }

any solution???

Note : i am giving this application to user in pen drive so i placed all needed software setup in pen drive itself.

Answer 1

Creating your own installer for an application is a time consuming and error prone process which doesn't make sense to deal with, considering the multitude of installers that already exist.

My personal recommendation would be to examine the Windows Installer XML Toolkit (WiX). It is completely free, and allows you to build a completely customized installer/uninstaller with external packages, with integration directly in Visual Studio.

Trying to do this by hand is not as simple as detecting a registry key; you must deal with out of date versions, file permissions, installation options, the possibility that the program may not exist on the system even though the registry key exists (just to name a few hurdles). WiX will manage your program version and external dependencies by using the power of the Windows Installer Database Engine.

It's to late but got the answer and your question is also very helpfull to me so thank you :)

var keyName = @"SOFTWARE\Microsoft\Silverlight";
            using (var regKey = Registry.LocalMachine.OpenSubKey(keyName))
            {
                var version = regKey.GetValue("Version");
                if (version + "" == "5.1.30514.0")
                {
                    MessageBox.Show("Installed");
                }
                else
                {
                    MessageBox.Show("Uninstalled");
                }
                var DisplayName = regKey.GetValue("DisplayName");
                lsitBox1.Items.Add(version);
                // lsitBox1.Items.Add(DisplayName);
            }
