Have a user that was using xp, office 2007 and had no issues opening a .TXT file for editing. When clicking on it, it will give you an option, read only or Edit. If edit, then the file would open as a text file. upgraded user to office 2010, windows 7, 64 bit. When clicking that file at first it will give him this message, "The document could not be opened for editing. A Microsoft SharePoint Foundation compatible application could not be found to edit the document". I got past that, by changing the default program to use when opening .txt files to use notepad. Now it doesn't give me that message, rather now it opens up as a webpage. Not a txt file. What gives?
