Previously, we discussed a workaround when you get the error " A version of the software required to install this update was not found on this volume" that involved copying the installer to your desktop. You can also get this error if you have modified Office or your system files.
Have you "trimmed the fat" on your computer? Have you run a language pack utility to save disk space? What about Monolingual, Safari fix or Xslimmer? Office for Mac 2008 Installer will install both sets of code (Intel/PPC). Did you strip out the additional code? All of these modifications can cause your update to fail.
Did you rename Microsoft Word to Word 2008? (name, location, and items in the folder have to remain the same as installed) Did you move any Office components? If you rename or modify any of the files in the Microsoft Office 2008 folder, you cannot install product updates.
Did you install and then immediately upgrade without restarting? The update usually fails on Tiger, but it will not always fail and it will not always pass on Leopard. Best Advice: restart and be safe.
Fix when you have modified files:
- Quit all applications. (Easy way: log out/in with Shift key down to disable any startup items.)
- Drag the Microsoft Office 2008 folder to the Trash.
- Empty Trash.
- Reinstall Office 2008 from your original installation disk. See details
- Restart (restarting before you launch any Office app is important!)
- Update
- Restart
- Repair Permissions. How-to
More details on modifying files is described here.
