Error 80070663 when updating Office 2013 on Windows 7 x64


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.



I may post this at the top of the thread, too, so that others looking for a solution can find this...

I too, had the problem of Failed Updates error 80070663

I tried manual updating from the individual downloadable files. These would fail immediately with a "product detection" failure message.

While looking for a solution on-line (including here), I too tried the Office 2013 Change>Repair option from Control Panel

After a reboot, I was able to successfully apply all updates.
