Method 1: Provide the original source that you used to install the program the first time

When you receive the error message that is mentioned in the "Symptoms" section, perform one of the following steps to provide the original source that you used to install the program:

•	Insert the original Office 2003 program CD that you used to install Office 2003, and then click OK.
•	Click Browse, locate the Office 2003 program installation folder on the network, and then click OK.

Although these steps resolve the requirement for the installation source files and allow for the update to continue, this problem may occur the next time that you try to update an Office 2003 program from the Office Update Web site.

Note If the steps listed in Method 1 do not work, it is possible that the files in the MSOCache\All Users\download code folder do not match the files on the CD that you have provided. Check to make sure that the CD that you inserted matches the product that is being requested. For example, the installed product may be Microsoft Office Professional Edition 2003 and the CD contains files for Microsoft Office Professional Enterprise Edition 2003. If this is the case, you must remove the Microsoft Office product, and then install the product again from the available CD.

Method 2: Use Office Update

Microsoft Update is designed to install an update without user interaction. For example, if you use Microsoft Update, you do not have to provide the program CD. However, if you use Office Update, you are prompted for your program CD-ROM only if there is a problem with the Local Installation Source on the computer.

To have the Office Update Web site detect the required updates that you must install on your computer, visit the following Microsoft Web site:

To use the Microsoft Download Center, visit the following Microsoft Web site: To search for the update that you want to install, follow these steps:

2.	Locate and then click the update that you want to install.
