Technote Details :: Can't open CHM file/ CHM topics are blank

Issue

After opening a CHM documentation file, a topic may not appear when you click a link from the Table of Contents. Also, when you try to use a Universal Naming Convention (UNC) path to open a .CHM file that exists on a network shared folder, topics in the .chm file may not appear.

CHM topics do not display

Reason

You are using Microsoft Windows XP and have installed Security Update 896358 from Microsoft, which prevents the features of some web applications to work properly.

Solution

Please read and follow the instructions under Method 2 described in this technical note from the Microsoft Knowledge Base. You will need to perform some changes to your registry.

Caution: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. InterAKT Online cannot be held responsible for any damages you may cause to your system by using the Registry Editor. You are on your own risk.

Using the 'Unblock' option in the properties window only appears to work if the .chm file is on the local computer. If the file is on a network computer/server, it has no effect.

On Windows XP (with the security update applied) you can also simply right-click on the CHM file, select Properties, and click on the "Unblock" button. Click "Apply" and the content should be visible.
