Hi,

I have used VSTO 2005 to create an Outlook 2003 add-in which depends on a
custom template (*.oft).

In my setup project, I have kept the default installation folder for the
add-in to [Program Files]\[Company Name]\[Product Name] and therefore the
template installs to a subfolder called Template.

The problem I have is when I want to load the template from my code, as
shown in the snippet below:

using Ol = Microsoft.Office.Interop.Outlook;
using Mso = Microsoft.Office.Core;
private void OnButtonClick(Mso.CommandBarButton button, ref bool
cancelDefault)
{
           // Open the custom form and display it to the user.
           Ol.Application _app = (Ol.Application)button.Application;
           
           string templatePath =
String.Format(Constants.DefaultTemplatePath, Application.StartupPath,
Constants.DefaultTemplateName);
           Ol.MailItem item =
(Ol.MailItem)_app.CreateItemFromTemplate(templatePath, Type.Missing);

           item.Display(false);
}

The issue is that Application.StartupPath returns the path to where MS
Outlook 2003 is installed (C:\Program Files\Microsoft\Office\Office11) not
the path to where my add-in is installed.

Is there any way to programmatically reference the location where the add-in
is running from?

Regards,
