ODF Add-in for Word

Double click the "OdfAddInForWordSetup-en-1.0.exe" file

If installation is successful, you should be able to open an ".ODT" file from Microsoft Word (see menu"File>ODF..."). Also, when right-clicking on a ".ODT" file in explorer, you should have the option to open the document in Microsoft Word (menu "Open with Word").

Important note: The ODF file opened by the add-in is imported in Microsoft Word as a read-only .DOCX file. If you want to save it as ODF, you will have to first make a copy of the document("Menu>Save As") and then use the "Export as ODF" menu.
