Browse Sequence Not Appearing in RH 2015

Hi there

Browse Sequences in CHM output are kind of tricksy and fraught with potential pitfalls.

Generically, you edit the window properties and ensure the Browse Sequences are configured. You report that you have done this. Good!

Next up is to ensure you have actually created at least one Browse Sequence. You also report you have done this. Good!

There are many applications that are capable of producing CHM output. And in the CHM output produced by RoboHelp, RoboHelp is rather unique among them. To the best of my knowledge, it's the only HAT that offers Browse Sequences in the way RoboHelp does it by modifying the window. This all happens because of a very special file named HHActiveX.dll. And here's where it gets kind of confusing and messy. There are two versions of this file. One for 32 bit versions of the Windows operating systems and one for the 64 bit versions of the Windows operating systems.

See, with the advent of newer computers and huge memory pools, Windows now offers two different versions of the HTML Help (CHM) viewer. A 32 bit version and a 64 bit version. Hence the need for a 32 bit version and a 64 bit version of the HHActiveX.dll file.

This HHActiveX,dll file(s) must be copied to the computer to different folders and registered with the Windows operating system so it knows how to work with it. And to muddy waters further, you can have none, only one version or both versions registered on a 64 bit system. So if perhaps it is registered for the 64 bit and not the 32, you *SHOULD* see the sequences when viewing the CHM in its 64 bit CHM viewer but it would be woefully absent if you were viewing the CHM using the 32 bit CHM viewer. So you need to ensure that you have the correct version of the DLL present and registered. (That means that if you are shipping the CHM file, you need to ensure both versions of the HHActiveX.dll are shipped along with your CHM and that they are registered on your end users' operating systems.

Here on my own PC, as I was trying to sort this, I'm seeing all manner of issues getting my HHActiveX.dll files registered. Looks like I need to ping Adobe and see what's up. You may encounter the same if you are on Windows 10. The general steps are to copy the files, then run the registry editor

Now let's turn to WebHelp output. While no special DLL is required, there are actually at least TWO (and sometimes more) places you must enable the Browse Sequences. So look at your WebHelp recipe and expand the Content Categories area on the left side. If you only have a single Content Category defined, click on the single category that should appear indented below. Then make sure the Browse sequence is enabled as shown below.

*NOTE: If you have more than one category, you need to repeat this process for each category.

Likely you overlooked that step above and that should resolve the WebHelp output.

In case the place above is where you were looking, here is the second place you must enable them.

Click Navigation on the left and ensure you place a check mark in the "Enable Browse Sequence" option.

Hope this helps you sort it!
