LegalCopyRight is always empty in FileVersionInfo C#?

Question

I have a SFX(self-extracting executable) file in windows (Created with zip tools like 7z, WinRar, ....) with the following details:

I want to get CopyRight text in C#, So I wrote the following code:

var fileVersionInfo = FileVersionInfo.GetVersionInfo(filePath);
Console.Write(fileVersionInfo.LegalCopyright)

fileVersionInfo.LegalCopyright is always empty! What's the problem?

Edit:
My original Code:

var fileVersionInfo = FileVersionInfo.GetVersionInfo(filePath1);
var properties = typeof(FileVersionInfo).GetProperties(BindingFlags.Public | BindingFlags.Instance);
foreach (var propertyInfo in properties)
{
    var value = propertyInfo.GetValue(fileVersionInfo);
    Console.WriteLine("{0} = {1}", propertyInfo.Name, value);
}
Console.ReadKey();

The result:

Finally I could find a solution:
1. First install the following package:

Microsoft.WindowsAPICodePack.Shell

It has a dependency package, Nuget install it automatically Microsoft.WindowsAPICodePack.Core

2. Now we can get file properties as the following code

using System;
using System.Reflection;
using Microsoft.WindowsAPICodePack.Shell.PropertySystem;

namespace ConsoleApplication1
{
    internal class Program
    {
        private static void Main()
        {
            const string filePath1 = @"C:\Users\Mohammad\Downloads\Test\.....exe";
            var shellFile = Microsoft.WindowsAPICodePack.Shell.ShellObject.FromParsingName(filePath1);
            foreach (var propertyInfo in typeof(ShellProperties.PropertySystem).GetProperties(BindingFlags.Public | BindingFlags.Instance))
            {
                var shellProperty = propertyInfo.GetValue(shellFile.Properties.System, null) as IShellProperty;
                if (shellProperty?.ValueAsObject == null) continue;
                var shellPropertyValues = shellProperty.ValueAsObject as object[];
                if (shellPropertyValues != null && shellPropertyValues.Length > 0)
                {
                    foreach (var shellPropertyValue in shellPropertyValues)
                        Console.WriteLine("{0} = {1}", propertyInfo.Name, shellPropertyValue);
                }
                else
                    Console.WriteLine("{0} = {1}", propertyInfo.Name, shellProperty.ValueAsObject);
            }
            Console.ReadKey();
        }
    }
}
