Browse to exe and create shortcut

What I desire to do is that in a click of a button the user gets to choose executable file to which he wants to create a shortcut.
 
For example we have the game Doom 3 in the folder "c:\games\doom3\doom.exe"
He would then pick the executable, click on OK, then in the form click on "save", and a shortcut to that executable would appear in the folder "c:\shortcuts\"
 
I lurked around for a while and found a sample code in how to create a shortcut but I have no idea how I'm going to do it just like I explained above.
 

WshShell shell = new WshShell();
 
            IWshShortcut shortcut = (IWshShortcut)shell.CreateShortcut(@"D:\shotcut.lnk");
 
            shortcut.TargetPath = Application.ExecutablePath;
            //shortcut.IconLocation = 'Location of  iCon you want to set";

            // add Description of Short cut
            shortcut.Description = "Any Description here ";
 
            // save it / create
            shortcut.Save();

 
I also tried this code and it would give an exception on "shortcut.Save", is it because I'm using a 64 bit system?
 
Thanks in advance.
