Microsoft find the solution :

Rebuild the registry keys
regsvr32 /u "C:\winnt\system32\itss.dll"
regsvr32 /u "C:\winnt\system32\itircl.dll"
regsvr32 /u "C:\winnt\system32\hhctrl.ocx"
regsvr32 /u "C:\winnt\system32\hhtctrl.ocx"

regsvr32 "C:\winnt\system32\itss.dll"
regsvr32 "C:\winnt\system32\itircl.dll"
regsvr32 "C:\winnt\system32\hhctrl.ocx"
regsvr32 "C:\winnt\system32\hhtctrl.ocx"

Let me know

Eric

I checked my own PC for these files, but I'm running WinXp Pro, SP2.
These are found in
"C:\WINDOWS\system32\itss.dll"
"C:\WINDOWS\system32\itircl.dll"
"C:\WINDOWS\system32\hhctrl.ocx"
"C:\WINDOWS\system32\hhtctrl.ocx"
on a WinXP m/c

I found three of the four, the missing one is 'hhtctrl.ocx', but again I'm not sure that WinXp usues it. All refernces to this file in Microsoft.com refer to earlier Op sys's.

Like you I need to read the help files in certain programs - and not being able to is really annoying

Regards

Greg.

I don't understand what it means to rebuild the registry. How do I do that? I am using windows 2000 pro.

I don't know, I wish I did, I know who to look in it and do some (limited) mods to it, but I've now idea how to "re-build it"

I am using windows 2000 pro. One more thing. I also checked for those files and I am missing the same one.

But does Win2K use it? All references to this file in Microsoft.com refer to earlier Op sys's.

I'm lost - I was hoping my posts would help Metallica by providing extra information, I'm in the same position as you - looking for the solution, I'm no expert.

opend a command prompt and paste juste this

regsvr32 /u /s itss.dll
regsvr32 /u /s itircl.dll
regsvr32 /u /s hhctrl.ocx

regsvr32  itss.dll
regsvr32  itircl.dll
regsvr32  hhctrl.ocx

After i do that, the Cannot oppen file.... disapeare and my help work again...

BINGO !!!!

For me, with Windows XP Pro & SP2 all I needed was the second set ......... these ...>>

regsvr32 itss.dll
regsvr32 itircl.dll
regsvr32 hhctrl.ocx


Not sure what the first top set are about (the ones with the /u /s in them)?? But I'd be interested to know?

But I now have ALL my help files back .........

Many Many Thanks to you all.

I am seeing another person saying to rebuild the registry. Can anyone tell me how or what that means? I did what Greg suggested about the command prompt. I still cannot open any help and I still get the same message.

[Robodick]

Well PigPower's solution worked for me, just follow the below .......

Copy each of the following lines one at a time, in turn (copy & paste etc with mouse)

regsvr32 itss.dll
regsvr32 itircl.dll
regsvr32 hhctrl.ocx

Then Click Start - Click Run - and paste what you just copied into the "open" window - click OK - and after a few seconds you should get a dialog returned saying:- "DllRegisterServer in itss.dll succeeded."

Repeat for the second and third line and it should work, you should be able to view your help files once again, it did work for me.

Hope it does for you as well.

Let us know?

Regards Greg.

Hi,

If you can't open chm files try running:

MJ's Help Diagnostics
from: http://helpware.net/downloads/

It worked for me in win XP

Good luck!

Thank you so much SimioDesnudo for the link. MJ's Help Diagnostics solved my all problems with CHM files.

MJ's Diagnostics is a small utility that reports if all the HTML Help runtime DLLs are installed and registered correctly. If a DLL is not registered then it will ask if you want to register it. It also checks the RoboHelp DLL (HHActiveX.dll) and MS Help 2 DLLs.

Great application. Thanks....

Just a quick note of thanks to PigPower...had the same problem with my MSDN library, after trying to install a CAD program (no relation to each other, the CAD install went and reset a lot of file associations, etc.). Your advice worked, and I now have my MSDN library back.

Just wanted to thank you for your help. I was having the same problem and was ready to reinstall Windows when I found this advice via Google and solved the problem. I am now a registered User.
