Microsoft has released an update that eliminates a security vulnerability in Microsoft Excel 2000 and PowerPoint 2000. This update, the Microsoft Excel and PowerPoint 2000 SR-1 Add-In Security Update, eliminates a security vulnerability that could allow unsafe scripts to be run in Microsoft Excel 2000 or Microsoft PowerPoint 2000 when you view a Web page or HTML e-mail message. This update makes changes to the registry and eliminates the ability to run unsafe Excel or PowerPoint scripts by using the Internet Explorer Object Model.
NOTE: There are two separate updates: one for both PowerPoint 2000 and Excel 2000, and the other for PowerPoint 97. Excel 97 is not affected by this vulnerability.

How to Download and Install the Update
To install the update, you must have access to your original PowerPoint or Office CD. (One exception is if you installed from a "flat copy" of the CD stored on a network server. A "flat copy" is not the same as an administrative installation.)If you installed from a network administrative installation to your workstation, you should contact your administrator about obtaining this update. Do not attempt to apply this update to your workstation.
Follow these steps to download and install the update:
The only changes made to Microsoft PowerPoint 2000 are in the registry. However, if you also have Microsoft Excel 2000 installed, you can verify installation by checking the version of Excel.exe.
To verify whether the installation of the update was successful, you can check that the version of the Excel.exe file on your system is equal to or greater than 9.0.4307. By default, Excel.exe is in the following location on your computer:
C:\Program Files\Microsoft Office\Office
