Update Your Clients Where Office Is Already Installed

Use a Command Line

1. Click Start, and then click Run.
2. In the Open box, type a command line similar to the following, and then click OK.
   
   NOTE: The following command should be all on one line.
   msiexec /i path\Data1.msi Reinstall=OutlookCDO ReinstallMode=vemus
   NOTE: The OutlookCDO parameter must be typed exactly as it appears in the above step.
3. Click OK to the message that Setup completed successfully.
4. Click Yes to restart the computer if prompted.

Use Maintenance Mode Setup

If you prefer to use Maintenance Mode Setup instead of a command line to update your network client, follow these steps:

1. Click Start, point to Settings, and then click Control Panel.
2. In Control Panel, double-click Add/Remove Programs.
3. In the Add/Remove Programs Properties dialog box, double-click the name of your Office 2000 product.
