Fixing error "You are attempting to open a file type that is blocked by your registry policy setting"

When you try to open a presentation that was saved in a Microsoft PowerPoint format, the presentation does not open. Additionally, you receive the following error message:

You are attempting to open a file type that is blocked by your registry policy setting.

This issue may occur if an administrator has restricted the types of presentations that you can open in Microsoft Office PowerPoint 2007 or in Microsoft Office PowerPoint 2003. An administrator can set a registry key to restrict this functionality.

FIX:

To resolve this issue, disable the restriction on opening presentations that were blocked by the registry settings of PowerPoint. To do this, use one of the following methods.

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.

Use a trusted location, or create an exempt location

* In PowerPoint 2007, if you trust the file that you want to open, you can move the file to a trusted location to override the registry policy settings.

For more information about how to create, to remove, or to change a trusted location for files, visit the following Microsoft Web site:

* In PowerPoint 2003, there are no trusted locations. You can create an exempt location to override the registry policy settings. To create an exempt location, follow these steps:

1. Exit PowerPoint 2003 or PowerPoint 2007.
2. Click Start, click Run, type regedit in the Open box, and then click OK.
3. Locate and then click one of the following registry subkeys:
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Common
4. On the Edit menu, point to New, and then click Key.
5. Type OICEExemptions for the name for the key.
6. On the Edit menu, point to New, and then click String Value.
7. Type a string name, and then press ENTER. For example, type ExemptDirectory.
8. Right-click the string name that you typed in step 7, and then click Modify.
9. In the Value data box, type the path of the directory that contains the file, and then click OK.

For example, if your document is in the C:\My Documents folder, type C:\My Documents in the Value data box.

Note You must create the folder. Any subfolders are not automatically exempted. For any additional folders that you would like to make exempt, repeat steps 6 to 9 by creating string values such as "ExemptDirectory1" and "ExemptDirectory2."

10. On the File menu, click Exit to exit Registry Editor.
