I download the 'Windows Help' file for '.NET Data Provider 14.10.00.00' at
The downloaded file 'tdnetdp__windows_indep.14.10.00.00_help.chm' is 7MB,
however when I open the .chm file, I can see the Index but not the contents
The content pane says 'Navigation to the webpage was canceled'
It worked for me now after I
right click the .chm file -> Properties -> Uncheck attribute 'Read-only' -> click 'Unblock'
Since I downloaded the file from internet it was 'Blocked'
