|If you are unable to solve this, you might as well try the following.|
(It is a long shot, and I guarantee nothing.)
(It may fail as spectacular as it succeeds.)
You say you have SP3.
Go to http://blogs.msdn.com/b/heaths/arch... and download msix.zip
Extract that to wherever.
"C:\New Folder" should work.
Create another folder in "C:\New Folder".
I simply called it "Test".
Open SP3 in any Zip program.
(Both WinRAR and PowerArchiver will open it.)
Open, not run.
Extract "MAINSP3.msp" from "Office2003 SP3.exe".
Place "MAINSP3.msp" in "C:\New Folder".
In "C:\New Folder" you will have:
In "msix" you will have "Release".
Inside "Release" is:
Now, you will need to drop to a Command Prompt.
The Command Prompt will probably be at "C:\Windows\System32\".
(It doesn't really matter.)
cd "New Folder\msix\release"
Your Prompt should now read:
MsiX.exe ..\..\MAINSP3.msp /out ..\..\Test\ /ext
It should run through a bunch of file names.
The last file name will be "PCW_CAB_H15000_1.cab".
That's the one we want.
You can close the Command Prompt Window.
Now, go to "C:\New Folder\Test".
Rename it to "ZF612707.CAB".
Point your installer to it when asked.
If that doesn't work, move the file ("ZF612707.CAB") to "C:\MSOCache" and run the installer again.
Hopefully it works.
