I use Office 2003 at home and the office. Unfortunately, Microsoft decided to modify the default format used to save files in the new version 2007 of its office suite. When using older versions of Microsoft Office, you have to have a converter pack loaded or the file will fail to open. Sometimes things go haywire with the converter pack, as I found out last week when every .xlsx (Excel 2007) file I was given, failed to open
I had loaded the Office converter pack and it worked ok for the first few days. The file I needed was accessible and I forgot I even had the converters loaded. Then, last week, I needed to open more of the .xlsx files and the converter kept returning the extremely descriptive error: “The converter failed to save the file“.
I tried repairing office, rebooting and reinstalling the converter pack, but it did no good. I used Filemon and Regmon to find out what the converters were trying to access and where it was trying to save the temporary file by default. Again, nothing of note.
Finally, I discovered Microsoft has released the Office Compatibility pack SP1. Reinstalling this, fixed the problem immediately.
