Well, hotfixes.reg is not designed to be in local cache. When this failure happens. During install? Or when you try to launch something from cache?
Not a real failure, but only an error message box that appears at the end of the installation process, which is completed successfully and without problems: Office is installed and configured correctly, with all my personal settings activated and functioning properly.
The error message is generated by REGEDIT, right at the end of the setup, when HOTFIXES.REG should be added to the registry.
Only THIS operation fails, and the registry does not get updated.
After adding manually HOTFIXES.REG (doubleclicking on it) and after a healthy reboot, MS Update says I still need these 3 "obsolete" updates:
KB955434 (OLK FLT, August versione replaced by Sept. ver.),
KB950241 (WORD, 05/13/2008 ver., replaced)
KB943985V2 (EXCEL 03/19/2008 ver., replaced)
You mean, that those hotfixes are not on the list, or? From the log I see that you did not integrate it, so you probably mean on the list of updates?
Those hotfixes are not on your (and mine) list of updates, because they were replaced by newer hotfixes.
I did a Direct Slipstream using version 1.7.2 with SP3 and the 15 hot fixes of your list of updates, adding the 3 new updates of September, and removing older version of the Outlook Filters.
I made three tests, all with the same result.
After installing the 3 updates reported, MS Update was happy and said "no updates available".
