Can you tell us what the file extension is?
The error message indicates that you have not "associated" an application that should open that kind of file type. You can easily do this by going to the file itself, right clicking on it, and then going to Properties; the "general" tab will indicate the file type, and what (if any in your case) it "opens with:".
Now, if you click on the "change" button, you should get another box that lists available applications from which you can choose. Once you have decided and highlighted the correct application, be sure to check the box underneath the list that says "always use this program to open files of this type" (or something very close, depending on your version of Windows) and then click on "OK."
Hope this helps- - -but if you have questions, don't hesitate to reply.
Whereof one cannot speak, thereof one should be silent.
