The reason that it does not say “Advanced” is symptomatic of the reason why you cannot open these files from your desktop. Try this:
In the same Files Types tab you were speaking of, select New.
- Select Advanced and in the drop down select Microsoft Office Word 97 – 2003 Document.
- Click Okay.
- Click Yes if it tells you to it is already associated with the File Type (because in essence you are just ‘re-associating’ it)
- Now try to open up those documents on your desktop.
Let us know how it goes. Good luck.
