Have you ever downloaded a help file (.chm extention) and couldn’t read the content? I had this issue a few weeks back when I had to check something in the “Installation Team Foundation Installation Guide for Visual Studio 2010”. I had to think a few seconds before I remembered that I needed to unblock the content.
- Open Windows Explorer
- Right-click .chm file and select Properties
- Choose Unblock
…and the content is readable.
