Recently we upgraded from Office 2003 to Office 2010. After the upgrade, 1 of our users does not have Excel listed in the default list of “Open” programs when he tries to open a file without an extension. I’ve browsed to the Office14 folder, Excel.exe, and click Open but Excel does not get added to the list. OS is XP SP3. Is there a registry entry I can manually add the excel executable to so he can use it to open files without extensions?
