Every page shows "The page cannot be displayed". I get the error before and after running StrataFrameHelp.exe and also both on my laptop and desktop.

This is because you have a "patch" on your machine from the Microsoft Update service that blocks all CHM pages by default.  To resolve this error, right-click on the CHM file and go to properties.  Once the property dialog opens, there will be a button at the bottom right that says "unblock."  Click this and then OK.  You will then be able to see the pages just fine.
