I am encountering error 80070663 when trying to update Office 2013 on Windows 7 x64. 9 updates do not install: 2863910, 2752087, 2817636, 2825631, 2827272, 2863864, 2817628, 2837627, and 2817301.
Several updates to Microsoft Office 2013 overall install correctly and the problem seems to reside with updates to the various Office applications (Excell, Word etc.)
I have followed to the letter all the suggestions I've seen in other threats -- checking services, fixing registries, clean boot install, creating new admin account, etc... to no avail. I have also system restored the computer to earlier statuses and tried again -- again, to no avail.
I have a sense that the problem might be with Office 2013 rather than with Windows Update, but I am not an expert.
Any suggestions, please let me know. I greatly appreciate your help.
