I just downloaded Technet Magazine – January 2007 HTML help file and when I opened, I noticed the topics in the .chm file cannot be viewed and I realized that it was getting blocked and all I had to do is to unblock the file (see the procedure below) and this time I can see the contents happily:-)
| 1. | Right-click the CHM file, and then click Properties. |
| 2. | Click Unblock. |
| 3. | Double-click the .chm file to open the file. |
