SYMPTOMS

When you click a link to a Tagged Image File Format (TIF, TIFF) image in Internet Explorer, you may be prompted to either open the file directly or save the file. Note that this may occur even though you previously clicked to clear the Always ask before opening this type of file check box. Also note that the issue that is described in this article is specific to users who previously clicked to clear the Always ask before opening this type of file check box.

CAUSE

In the Registry, both TIFImage.Document (the default ProgID for the .tif and .tiff file extensions) and Imaging.Document point to the same CLSID. However, this CLSID only refers back to one ProgID (which is Imaging.Document).

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, use Registry Editor to view the following registry subkey:

HKEY_CLASSES_ROOT\.tif

In the right pane of Registry Editor, right-click (Default), and then click Modify. In the Value data box, type the following value, and then click OK:

Imaging.Document

Use Registry Editor to view the following registry subkey:

HKEY_CLASSES_ROOT\.tiff

In the right pane of Registry Editor, right-click (Default), and then click Modify. In the Value data box, type the following value, and then click OK:

Imaging.Document

Quit Registry Editor.

IMPORTANT: If you use a graphics viewer that supports Tagged Image File Format (TIFF) files (for example, Microsoft Imaging in Windows 2000), then any of the registry values that are listed in the "Cause" section may be changed. As a result, this problem may reoccur.
