I have many updates for office 2013 installed on windows 8 pro yesterday I want to ask why the office version number is different : From office: file:account: about : version number is 15.0.4517.1504 while in add/remove program list in control panel it is still the same: 15.0.4420.1017 (not changed) Why this difference is present ? and why version number is not the same ? do I miss something? all updates are installed successfully without problems
