How can I increase the success rate of installing Office 2000 updates?
Install Office2000-kb835220-client-enu.exe from Microsoft before installing other Office 2000 updates.
Microsoft has released an update to Microsoft Office 2000. By installing this optional update, the MsiFileHash table for your Microsoft Office product is updated. Updating the MsiFileHash table will help Office reduce the chance that the Office Setup program will need access to your Office 2000 source CD-ROM when you install Office updates in certain scenarios. Additionally, by updating the MsiFileHash table, the need to copy files from your source will be reduced, resulting in faster file copy (when necessary) and reduced network traffic (when applicable) (http://support.microsoft.com/default.aspx?kbid=835220).
