One little bit frustrating thing is that Vibe Add-in for Microsoft Office in my thinking too early gave up on MS Office 2003! We still have it installed on most of devices and it does very good job and in most cases upgrading to newer Office is a waste of money. But, as in system requirements for Vibe Add-in is stated and via setup is noted -- Office 2007 and 2010 is only supported versions. Too bad, must admit. Mh, also, in my opinion they should have first (or at same time) release add-in (extension) for LibreOffice, have they! Although I managed to install it along with standalone Office 2003 and so far ... no problem. Previously I tried it on system where both Office 2010 and 2003 is installed.
