Class not registered error when reading CHM

[Vadim Roulnov]

Hi all,

When I click on a hyperlink of some sort in a .CHM (compiled help) file I
got error message:
'Class not registered'. I have decompiled the .CHM file and detected that
the problem is where function JavaScript:ShowPopup is called.

This .CHM file can be read on another computer without problems.

I use Win2000 SP4 with IE 6.0 SP1. I have reinstalled SP4 of Win2000 and IE,
but it without success.

Could anyone help me to fix the problem?

-Vadim

Vadim,

When I click on a hyperlink of some sort in a .CHM (compiled help) file
I got error message: 'Class not registered'. I have decompiled the .CHM
file and detected that the problem is where function JavaScript:ShowPopup
is called.

This .CHM file can be read on another computer without problems.

I use Win2000 SP4 with IE 6.0 SP1.

You may be able to fix this problem by unregistering and then
re-registering the HTML Help ActiveX control (hhctrl.ocx). To do this,
open a Command Prompt window and then enter the following two
commands:

regsvr32 /u %windir%\system32\hhctrl.ocx
regsvr32 %windir%\system32\hhctrl.ocx

If the problem persists, try running MJ's Help Diagnostics, which is
available from here:

(The only section of the MJ's Help Report that is relevant to your
problem is the one headed "HTML Help Run-time Components".)
