Unable to read downloaded compiled help (CHM) files?

A problem I keep running into and forgetting how to solve, so I will jot it down here for future reference.

You download some compiled help (*.chm) file from anywhere on the internet.  You open it and see the hierarchical Contents tree on the left panel, but no content on the right panel!

Steps to solve this:

  1. Open the files Properties
  2. Click the button Unblock, assuming it is displayed.
    • The button should disappear after you click it.
  3. Press OK.
You're good to go.

I think the reason the problem occurs is that later versions of Windows block them automatically as a security feature.   As with anything, make sure you are downloading them from a trusted site!
