Attach small ods file which will not open in MS Excel 2010 or 2007; on OS platform Windows7 of WindowsXP. Both Office suites already include add-in but we installed odfAddInforOfficeSetup v 4.0.5309. No repeat, only file we have. Error message permanent. Occurs always with this file. Conversion error. Will lose all date (40 hours research if we cannot resolve issue. (sorry, new to this, don't know what roundtrip means!)
