--- Comment #23 from Rosanne DiMesio dimesio@earthlink.net 2009-06-08 21:48:33 --- Tested with today's git and the patch submitted yesterday for bug 17600.
Office 2003 and fileformatconverter.exe both install fine with the patch.
The good news: it's fixed for Word 2003. I was able to open and create docx files with no problem.
The bad news: it's still not fixed for Powerpoint and Excel. Powerpoint complained about no filter being installed for the pptx filetype; Excel said the xlsx file was an unknown format and asked if I wanted to import it as text.
