That is a "security feature" from Microsoft. There was a security issue with HTML help, as described in this article MS05-026[^]. But there is a work-around for it. I had to write some docs for a project we're working on, in HTML Help format, and the help file was to be put on a network server for all to read. The solution involves editing registry keys, to allow the reader's system to open the file. Note that this solution actually degrades the security of your network. Anyhow, here's the sum up: In a .reg file:
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\HHRestrictions]
"MaxAllowedZone"=dword:00000000
"UrlAllowList"="<network path to CHM file(s)>"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000000
"UrlAllowList"="<network path to CHM file(s)>"
And by network path I mean the whole qualified path, without the file name itself. For example: \\SERVER\HELPDIR Note also that you'd have to escape the backslash character, so the above path would become: \\\\SERVER\\HELPDIR One catch... you'd have to apply this .reg file on every system that wants to access the help file(s).
