Find path of all software's starting with same Prefix name

Try the following which uses a class I found on StackOverflow (q.v.) to get the list of installed programs from the registry, though I've modified it to get the installation locations (where recorded) as well:

/* based on class written by Melnikovl in SO thread:

using System;

using System.Collections.Generic;

using Microsoft.Win32;

using System.Linq;

class Program

{

static void Main()

{

List details = InstalledPrograms.GetInstalledPrograms();

var query = from id in details group id by id.DisplayName.Split(' ')[0] into g select g;

foreach(var g in query)

{

Console.WriteLine(g.Key.ToUpper());

Console.WriteLine();

foreach(InstallationDetails id in g) Console.WriteLine(id);

}

Console.ReadKey();

}

public class InstallationDetails

{

public string DisplayName {get; set;}

public string InstallLocation {get; set;}

public override string ToString()

{

return String.Format("{0}\n{1}\n", DisplayName, InstallLocation);

}

public static class InstalledPrograms

{

const string registry_key = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";

public static List GetInstalledPrograms()

{

var result = new List();

result.AddRange(GetInstalledProgramsFromRegistry(RegistryView.Registry32));

result.AddRange(GetInstalledProgramsFromRegistry(RegistryView.Registry64));

return result;

}

private static IEnumerable GetInstalledProgramsFromRegistry(RegistryView registryView)

{

var result = new List();

using (RegistryKey key = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, registryView).OpenSubKey(registry_key))

{

foreach (string subkey_name in key.GetSubKeyNames())

{

using (RegistryKey subkey = key.OpenSubKey(subkey_name))

{

if(IsProgramVisible(subkey))

{

InstallationDetails id = new InstallationDetails

{

DisplayName = (string)subkey.GetValue("DisplayName"),

InstallLocation = (string)subkey.GetValue("InstallLocation")

};

result.Add(id);

}

return result;

}

private static bool IsProgramVisible(RegistryKey subkey)

{

var name = (string)subkey.GetValue("DisplayName");

var releaseType = (string)subkey.GetValue("ReleaseType");

//var unistallString = (string)subkey.GetValue("UninstallString");

var systemComponent = subkey.GetValue("SystemComponent");

var parentName = (string)subkey.GetValue("ParentDisplayName");

return

!string.IsNullOrEmpty(name)

&& string.IsNullOrEmpty(releaseType)

&& string.IsNullOrEmpty(parentName)

&& (systemComponent == null);

}

}

On my machine this produces a heck of a long list and you might therefore want to write it to a file rather than to the console.
