SUMMARY

This article contains information about certain file types that are blocked after you install Microsoft Office 2003 Service Pack 3 (SP3).

INTRODUCTION

This article contains detailed information about what file types are blocked by Office 2003 SP3 and about how to enable these file types.

MORE INFORMATION

File types that are blocked

After you install Office 2003 SP3, the following Microsoft Office Excel 2003 file types, Microsoft Office PowerPoint 2003 file types, and Microsoft Office Word 2003 file types are blocked. By default, these file types are blocked because the parsing code that Office 2003 uses to open and save the file types is less secure. Therefore, opening and saving these file types may pose a risk to you.

The following table contains the registry value names and the corresponding file types that are blocked from opening by default.

How to enable blocked file types

Important These steps may increase your security risk. These steps may also make the computer or the network more vulnerable to attack by malicious users or by malicious software such as viruses. We recommend the process that this article describes to enable programs to operate as they are designed to or to implement specific program capabilities. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this process in your particular environment. If you decide to implement this process, take any appropriate additional steps to help protect the system. We recommend that you use this process only if you really require this process.

To enable the blocked file types, use one of the following methods.

Method 1: Use a downloadable update to automatically re-enable all file types

Microsoft has created a set of updates to re-enable all file types. To install the updates, follow these steps,

  2. Double-click the file that you saved in step 1.
  3. Click Yes to confirm the installation of the file.
  4. If an Office program is running, restart the Office program.
After you install the update, the registry settings will be updated to allow you to open and to save all file types that are supported by Microsoft Office 2003. These file types include the file types that are blocked by default in Office 2003 SP3. The parsing code that is used to open and to save the file types is less secure. We recommend that you install these updates only if you need to work with the file types regularly.

Microsoft has also created a set of updates that will restore your registry settings to the settings as installed by Office 2003 SP3. To install the updates, follow these steps:
  1. Download the appropriate files from the Microsoft Download Center. To do this, click one or more of the following links:
  2. Double-click the file that you saved in step 1.
  3. Click Yes to confirm the installation of the file.
  4. If an Office program is running, restart the Office program.
Note After you install the update, the registry settings will be updated to the settings as installed by Office 2003 SP3. Additionally, you will no longer be able to open or to save the file types that are blocked by default in Office 2003 SP3.

Method 2: Use the Administrative Templates to set the registry keys

You can use the Administrative Templates in the "Office 2003 Service Pack 3 Administrative Template (ADM), OPAs, and Explain Text" update to set these registry keys.

To download this update, visit the following Microsoft Web site:

Method 3: Manually set the registry values

You can manually set the registry values to enable these file types in various products. To do this, follow these steps for the product that you are running.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
