error with chm files

[Silvio.Falconi]

I have a strange problem

When I call a file Help chm from an Fwh application I have a strange error

"Action canceled!" is displayed instead of the topic text.

I set the help file at main.prg with SetHelpfile("family.chm") and then on a menu HelpIndex()


I try to search on Internet If there are problems with new Windows and i found on a site this but I not understood

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"UrlAllowList"="u:\\productmanuals\\helpfiles;file://u:\\productmanuals\\helpfiles"


on another site I found
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000004


Some have had this problem ?

I have this error on Windows Xp professional and Windows Seven 64 bit
because at school I have Winxp and atHome i have Win764bit

On Winxp I not have the Unblock button
on link https://support.microsoft.com/it-it/kb/917607/es I found files mnu for Win7 x86 and x64 and this afternoon I try at Home
But I not found solution for Windows Xp
To create chm file I use Help & Manual 5

[Silvio.Falconi]

On Windows Xp I resolve with

WinExec ( "HH " + "namehlp.chm" )

But this solution is no good because I cannot use helptopic func to call a specific page



To Gurus

I think there is a Problem on functions Helpindex() and SetHelpfile("namehlp.chm")
and I think there's an error on Help32.prg or/and Helpchm.prg ( WinApi Folder)

I download the file Windows6.1-KB917607-x64 from Microsoft ( for seven 64 bit)
I close the pc and the n I open the pc ,remade the file chm and the module exe
I tried to press f1 and it make the same not run
I see allway the page black with the error "Action canceled!" is displayed instead of the topic text.

it not depend from Microsoft but the function of fwh/xharbour winapi
