In 2007 Office, when you click a hyperlink or an object that links to an executable file, you receive the following warning message: This behavior occurs regardless of your security level settings.

Note To locate your security level settings, point to Macro on the Tools menu, and then click Security.

Additionally, when you open either TIFF images or Microsoft Document Imaging (MDI) files, you receive the following warning message: You receive this warning message even when you have already implemented the registry key that this article describes. This warning message comes from the HLINK.dll file when link navigation is handled. You can differentiate the 2007 Office hyperlink warning message from the HLINK warning message by looking for quotation marks around the file path in the warning message. The 2007 Office message contains quotation marks. The HLINK message does not contain quotation marks. 2007 Office tries to determine whether the file type itself is unsafe by checking the extension, the progid, the classid, and the MIME type of the document.
