<div class="symptoms_section">

SYMPTOMS
You may receive a security warning similar to the following security warning when you try to access the Product Updates catalog from the Microsoft Windows Update Web site:

Do you want to install and run 'C:\\WindowsUpdate\ident.cab'? The publisher cannot be determined due to the problems below: File not found or not valid format.

Note The drive letter in this example is "C" but the actual drive letter may vary.

When you click Yes or No on the security warning, you may receive a "Cannot Display Page" error message.

<div class="cause_section">

CAUSE
This behavior may occur if the location of the Program Files folder has changed either by using a utility (such as Tweak UI) or the Windows Registry. Any change to the Program Files path that ends with a backward slash (for example, C:\) adds an additional backward slash to the install path of the Ident.cab file. As a result, the path is C:\\WindowsUpdate\Ident.cab instead of the correct path, C:\WindowsUpdate\Ident.cab.

<div class="resolution_section">

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 behavior, change the location of the Program Files folder to its default location of :\Program Files (for example: C:\Program Files) or specify a new location for Program Files. However, the path must include a specific folder and cannot end with a backward slash.

For example, change C:\ to C:\. To make this change, use Registry Editor. To do so, follow these steps: <ol> Start Registry Editor.</li> Locate, and then click the following key in the registry:

</li> In the Value pane, right-click ProgramFilesDir, and then click Modify.</li> In the Edit String window, make sure that the Value data box contains C:\Program Files.

If you have specified a different drive and path, make sure that the path you want includes a specific folder and does not end with a backward slash.</li> Exit Registry Editor, and then restart your computer.</li></ol>
