How to check if MSWord 2003 0r 2007 is installed in the system using C# code?


Solution:1

This code shows that a simple registry check will do the job.

Here is the code converted to C# (and slightly improved to use a using statement).

using Microsoft.Win32;    // Check whether Microsoft Word is installed on this computer,  // by searching the HKEY_CLASSES_ROOT\Word.Application key.  using (var regWord = Registry.ClassesRoot.OpenSubKey("Word.Application"))  {      if (regWord == null)      {          Console.WriteLine("Microsoft Word is not installed");      }      else      {          Console.WriteLine("Microsoft Word is installed");      }  }  

Note that it's not good enough to check C:\Program Files\Microsoft Office\ for the msword EXE file, as the user might have installed it somewhere else.


Solution:2

One of the solution, i reckon there should be better if you google it. To Check whether Excel is installed or not, I use this c# code

Excel.Application app = new Excel.ApplicationClass();  

if app == null that means excel is not installed on the machine.If you check the MSDN docs, you should be able to get the syntax for opening a word appln.
