Find all installed software of a system using C#.

I had tried to find all the software installed in my system using c#. There are several ways to find this. Initially I have tried using DOC command but some the software’s are not listing with this approach.

The below approach is worked fine for me. Reading Register data we can easily get all the data of install ed applications. The below code snippet will help us to identify the installed softwares.

//Declare the string to hold the list: 

string Software = null;

//The registry key: 

string SoftwareKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";

using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(SoftwareKey))

{

//Let's go through the registry keys and get the info we need: 

      foreach (string skName in rk.GetSubKeyNames())

        {

        using (RegistryKey sk = rk.OpenSubKey(skName))

           {

               try

                 {

                  //If the key has value, continue, if not, skip it: 

                  if (!(sk.GetValue("DisplayName") == null))

                   {

                     //Is the install location known? 

                      if (sk.GetValue("InstallLocation") == null)

                       Software += sk.GetValue("DisplayName") + " - Unknown Installed path \n"; //Nope, not here. 

                     else

                       Software += sk.GetValue("DisplayName") + " - " + sk.GetValue("Installed Location") + "\n"; //Yes, here it is... 

                   }

                   }

                  catch (Exception ex)

                  {}

                  }

                }

            }

            Console.Write(Software);

            Console.ReadLine();
