Not sure how to get around this particular permission problem. Here is something of a work-around of the top of my head.

1. open current document
2. select whole document
3. copy selection
4. Add new document
5. Paste whole selection into new document
6. SaveAs active document.

Code goes something like this: NOTE: Not tested so there may be errors!!!!

With oWord
.Open(D:\xfilename.doc,.f.,.t.)
.Selection.WholeStory
.Selection.Copy
oDocument.Add()
.Selection.Paste
.ActiveDocument.SaveAs(c:\Newfilename.rtf,100)
etc....
endwith
