This is an alternative for "How to Check Whether Word is Installed in the System or Not"

Introduction 

It is common to need to work with various Office applications using the Microsoft.Office.Interop.xxx namespaces where xxx is the Office application, e.g. Microsoft.Office.Interop.Word in order to do so, you must ensure that the appropriate application is installed on the client machine.  

Background 

Having read both of Tadit's excellent tips I decided that I would make a simple utility class to handle the logic for me - allowing me to reuse the code and optomise it over time if needed.

Using the code 

The utility class was added to my standard library, so that I can use it in multiple projects. 

using System;

namespace Me.Office.Common
{
    /// <summary>
    /// A group of Microsoft Office Utility methods
    /// </summary>
    public static class OfficeUtils
    {
        /// <summary>
        /// A utility method to check if Word is installed or not
        /// </summary>
        /// <returns>A Boolean value of whether Word is installed or not</returns>
        public static bool isWordInstalled()
        {
            return isApplicationInstalled("Word.Application");
        }
 
        /// <summary>
        /// A utility method to check if Excel is installed or not
        /// </summary>
        /// <returns>A Boolean value of whether Excel is installed or not</returns>
        public static bool isExcelInstalled()
        {
            return isApplicationInstalled("Excel.Application");
        }
 
        /// <summary>
        ///
        /// </summary>
        /// <param name="applicationName">The name of the application to be checked</param>
        /// <returns>A Boolean value of whether Application is installed or not</returns>
        private static bool isApplicationInstalled(string applicationName)
        {
            Type officeType = Type.GetTypeFromProgID(applicationName);
 
            return officeType != null;
        }
    }
}

This can be used in any other project as long as it is referenced correctly 

using Me.Office.Common;

namespace Me.TestHarness
{
  class Program
  {
    static void Main(string[] args)
    {
      bool isWordInsatlled = OfficeUtils.isWordInstalled();
      bool isExcelInsatlled = OfficeUtils.isExcelInstalled();
    }
  }
}
