What browser and operating system are you using?
Windows XP Pro SP 2, IE 6
I do get a “Security Warning” popup when I double click the .chm file
since you’re an “Unknown Publisher”. It asks if I want to “Open” or
“Cancel”. I select “Open”, but then I get the “Unable to Display”
errors.
If you are able to download the file, but then you get this error when
trying to open the file, yes this is something with the Security
Policy within your company. Sorry.
