First the the machine is an XP Pro SP3, with MS Office 2003 SP3. The problem is the file converter pack for office 2007 file extensions does not work. I have all the patches for both XP and Office, uninstalled then reinstalled the converter pack, still no luck. I have also disabled any plugins in office, and any Active X that was not signed by MS. I have not reinstalled the Office suite yet or tried to repair it either. The machine is free of spyware and viruses, but did find some questionable active x's but disabled them any ideas other than a total reformatt??
