Broken help file

A few weeks ago I received a mail of a customer who complained of the help file of the SDL Suite which did not correctly display on his new computer (while the same help file on his old computer worked as expected). Several mails and a few Google searches later it turned out that this is due to a "security feature" of newer versions of Windows.

Microsoft discovered in about 2005 a vulnerability of the help engine which allowed to execute remote code within a corrupted chm file (compiled help file). The security hole was "fixed" by an update which simply blocks the display of html pages in the help viewer and displays the misleading message "Navigation to the Website was canceled".

Well, thank you Microsoft, this message is really of big help. Thousands (if not millions) of Windows user will eventually bump into this problem without having a clue of the true nature of the problem....

Those who face the same problem maybe want to have a look at the SDL TechNotes where I published a simple solution to it.

  1. Yeah, I stumbled upon such problem recently. Since Microsoft didn't actually help, your link was a real helping hand. We've added the link to your solution on our Knowledge Base web-site.
    Thanks!
