I'm inclined to stay well away from those third-party utilities/cleaners/optimisers/converters, though, as some of them do more harm than good - a likelihood that rapidly increases with every different one you use.įailing all of the above, the only other possibilities you're left with are that you have (a) installed some other software that is incompatible with Office 2003 or (b) a PC with a hardware fault. Windows 2000, Windows 2000 Advanced Server, Windows 2000 Professional Edition, Windows 2000 Server, Windows 2000 Service Pack 2, Windows 2000 Service Pack 3, Windows 2000 Service. Your inability to save files in the later format suggests that is indeed the problem. Windows XP Professional and Office 2003 Professional: Better Together. If, having done all that, you're still unable to open Office 2007 files, that suggests there is an inherent fault in either the Office installation or the Compatibility Pack installation. You should also ensure you have the latest Windows Installer for XP installed - the Compatibility Pack also requires that Windows XP has the Windows XP Service Pack 3 installed.

To use the Compatibility Pack with Office 2003 you must have the Office Service Pack 3 installed. With a clean install and a fully-updated Office 2003 package, all you should need is the Compatibility Pack for Office 2007.
