How Do I Create An Association

Operating system: Windows Vista home premium.
I "am" on 'Inbox-Windows Live Mail'.
1) I click the "Attachment" icon.
2) A pop-up window appears:
"Do you want to open this file?", Name:ATT00031.dat TypeAT File
I click "open"
3) A pop-up window appears:
"This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel."
I click "OK"
4) I am back on 'Inbox-Windows Live Mail'.

Question: How do I create an association to open this file.
From Inger.

 

When you select a program to open it with, you check the box that says "always use the selected program to open this type of file?

 

These dat files are usually the result of a problem with the sender's email program. No file association is going to help, 'though you could open them with Notepad/Word Pad.
Notify your correspondent and suggest they look here:

Hi and welcome.


I have seen .dat files come from folks who send emails from Mac operating systems. One file is good to open, the other is a .dat file.
