.chm problem

copy the files on the desktop and then try

Is that stored in Network Drive?

[blueshift]

or your Help executable file must have been corrupted. Check for the file hh.exe and replace it with another.

Seems it is on a network drive. Try copying it to some local directory and start it.

hh.exe file is in the Windows directory if you are using WinXP. If you want, I will send a copy of my file to you.
Are you getting this problem now or you could open the file in past? Do you download those files using ftp??

I found it c:/windows directory using the inbuilt search tool of xp but now there is one more problem..i go to start--->and click Help and support..It doesnt open..I tried a lot of times but it doesnt ...

I went to run and typed services.msc and checked whether the help and support service is stopped but to my surprise it was on...I stopped and restarted it but didnt help...So i cant figure out what exactly has happened

Seems like your whole Windows may be under attack. lol
Do you use Sp2?
First reset all your settings in IE.(Restore to defaults). Theres a file helpctr.exe in WINDOWS\PCHEALTH\HELPCTR\Binaries folder. Chk if it runs from there.

Did you try if the problem was with this file only or with other files too.

try opening this file on someone else's PC. maybe the file is corrupt

If it opens in others pc then there is high possibility that your files are corrupt. Probably this may be due to sp2. Did you installed any kind of theme or patch like Autppatcher/Vista theme?
If your friend is having XP, then you can copy hh.exe and helpctr.exe from his pc or just ask me.

I once used Vista transformation pack but i uninstalled it coz it gave me some problems just after 2 days of its use...As u said i replaced both the files hh.exe and helpctr.exe with a new one but i have the same problem...Now coz of this just dont hint me reinstall the whole ****ing OS

Do you have WindowsXp hotfix 896358 installed? Uninstall it if you have.

If there is a file named hh.dat in \Documents and Settings\%username%\Application Data\Microsoft\HTML Help, delete it. Note its a hidden directory.


Check the registry if it works.
#For Help and support:
In Registry Editor, goto HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\App Paths\HELPCTR.EXE
If the key isn't there, right click and create a new key HELPCTR.EXE
It should have a value of C:\WINDOWS\PCHealth\HelpCtr\Binaries\HelpCtr.exe
Restart your pc.

#For chm files:
Goto HKEY_CLASSES_ROOT\chm.file\shell\open\command
The Default value for this entry should be: "C:\WINDOWS\hh.exe" %1
Next, go to: HKEY_CLASSES_ROOT\.chm
The Default value for this entry should be: chm.file
if none of the entries exist then create a new one.

Following link will be of help to you:

i uninstalled the hotfix which u said ...
but i dint find the file hh.dat which u said me to find in the directory \Documents and Settings\%username%\Application Data\Microsoft\HTML Help,

I saw that it was not hidden... and i checked the registry as u said ...and all was fine and nothing to be edited

The file hhctrl.ocx like they said, is actually in the system32 folder.

[rakeshishere]

The version of my hhctrl.ocx is 5.2.3790.2453 and i have IE-7 beta 3 installed so what am i supposed to do..

The microsoft website said----- "If a different version of Internet Explorer is installed, extract a new copy of Hhctrl.ocx from the Hhupd.cab file on the Internet Explorer CD, or install the latest update for Windows HTML Help"

So i updated my windows help..It didnt help me at all

[sakumar79]

Did you register the dll file as mentioned in the link I provided in the earlier post?

Run "regsvr c:\windows\system\hhctrl.ocx"

Arun

[royal]

are there any special characters in the filename or path ???

I had a folder called "C#" where I had some ebooks. I was unable to open any.

When I changed the name from "C#" to "C Sharp" , I could open them

Arun

when trying to register the dll file i get a msg that "cannot find the dll file hhctrl.ocx"

[sakumar79]

Then, locate the file and revise the command to show correct path... If it is in system32 folder, run "regsvr c:\windows\system32\hhctrl.ocx"

Its ok...I have reinstalled my OS

[nishant_nms]

I too had faced this problem sometimes ago. Then I asked Microsoft for help. Then they called me and asked me to uninstal SP2 and again to install it in safe mode. My XP had not got any service pack in itself. It needs to be installed manulay after installation of XP
