CAUSE This behavior can occur if the file Mso7enu.dll or Mso7sve.dll is moved, deleted, or corrupted.
NOTE: The file named in the error message is incorrect. The name should be Mso7enu.dll.
RESOLUTION To resolve this issue, re-install Microsoft Office 97. If the issue persists, locate a copy of Mso7enu.dll and Mso7sve.dll and copy them to the following location: Program Files\Microsoft Office\Office
I have used Find in Eplorer and file Mso7enu.dll are already there. However i cannot find the other named file Mso7sve.dll by the same method - is it this that has gone missing / corrupt? How do you get a further / replacement file?
