If everyone already have Microsoft Workplace installed, once you install OpenOffice it is going to commandeer your complete office data and attempt to open these people in the applications as an alternative to Microsoft Office.Even should you change the file associations returning to Microsoft Business office, OpenOffice will probably switch these individuals back without your permission another time just about any OpenOffice application opens.

The just cure will be to uninstall OpenOffice and go by means of and reset all the file associations back to Microsoft Company applications.
