How to get MS Word templates directory for another user?

Question

I'm using the following code to get the path where Word stores its templates:

WordTemplatePath:=WordApp.Options.DefaultFilePath[$00000002];

The problem is that this returns the path for the actual, logged-in user.

Is there a way to get the path for another user of the same Windows instance?

I need it so my installer program can install the templates used by my program for other users as well.
