Hi Chris,

If possible, send the log file to me for further research. My email address is .

At this point, follow the steps below to see if it works.

#1 check the Office 2007 installation
===============
1. Go to Control Panel Add or Remove Programs.
Go to Control Panel Programs Programs and Features.

2. Select Office 2007. Click Change. Choose Repair to repair it. Can it be finished properly?
3. If not, repair it from the Office 2007 installation CD. If it also doesn't work, there should be problem with the Office 2007
installation, refer to the following KB article to remove and reinstall Office 2007.
928218 How to uninstall the 2007 Office system if you cannot uninstall it by using the "Add or Remove Programs" feature
http://support.microsoft.com/default...b;EN-US;928218

Install the Office 2007 SP1 update again. If it doesn't work, go to next step.

#2 Install the latest version of Windows Installer
==========================
Patch deployment for the 2007 Office release system requires Microsoft Windows Installer 3.1. If you do not have the required Windows
Installer version, you might receive an error message similar to the following during installation:
"2007 Microsoft Office Suite Service Pack 1 (SP1) failed to install"

Download and install the latest version of the Windows Installer (Instmsiw.exe) from the following link.
http://www.microsoft.com/downloads/d...displaylang=en

#3 Make sure that you have sufficient free disk space on the Windows system drive.
==========================
Office 2007 Service Pack 1 (SP1) requires that you have at least 1.75 GB of free space on Windows Vista and at least 1.1 GB of free
space on other versions of Windows, much of which will be returned after the installation is complete.

#4 check the Local Install Source (LIS) for Office 2007
===============
Since all Office 2007 installs create a Local Install Source (LIS), updates such as SP1 will require this to be present and in good
condition to complete. If users have tried to recover hard disk space by removing all or part of the LIS (the MSOCache folder), it will
need to be repaired before applying SP1.

Please insert the Office 2007 installation CD (or access the original Office 2007 installation source) and then choose Repair to repair the
Office 2007 installation. It will restore the LIS.

If anything is unclear or if you have any other concerns, please don't hesitate to contact me.

Sincerely,

I'm getting errors in Event Log:

When installing via Microsoft Update:

Product: Microsoft Office Enterprise 2007 - Update '2007 Microsoft Office
Suite Service Pack 1 (SP1)' could not be installed. Error code 1603.
Additional information is available in the log file e:\tmp\MSI963d8.LOG.

Additionally, MU interface displays error 78F (???)

When I'm trying to install manually from extracted MSP:

Product: Microsoft Office Enterprise 2007 - Error 1935.During installation
component assembly {46174A62-FAFE-4BD6-9662-F9A9F588F034} error occured.
HRESULT: 0x80131047. Assembly inteface: IAssemblyCacheItem, function:
Commit, assembly name:
Microsoft.Office.InfoPath.Client.Internal.Host,fi leVersion="12.0.6215.1000",version="12.0.0.0000000 ",culture="neutral",publicKeyToken=
"71E9BCE111E9429C",processorArchitecture="MSIL "

I had to translate this error, it might not be 100% accurate.

I saw some solution about reinstaling or repairing NET Framework, but
solution is rather for XP, at least installing Net 1.1 doesn't change
anything.
I enabled logging, but I'm getting tons of junk in log files and nothing
conclusive.

I'm using Vista Ultimate and Office 2007 Enterprise, also Project 2007 and
Visio 2007 installed.

Thanks for any ideas.
Chris
