Stuck half way through fixing the XE4 help system

[Edwin Yip 154]

I need advise on solving the IDE help system not working issue, it's XE4 on Windows 7.

I don't know since when it stopped working, but the error is as following:

RAD Studio's help namespace is not defined. Please reinstall RAD Studio's documentation.
class not registered, ClassID: {314111F0-A502-11D2-BBCA-00C04F8EC294}

So I found the instruction from embt: https://support.embarcadero.com/article/43035

The help installer almost worked until I got the following error:

H2Reg.exe
** Error **
MS Help 2.x runtime files are not installed on this PC.
Installation/registration of Help files cannot proceed.

According to Google and a MS forum post, I need Visual Studio 2008 SDK which still has a download on cnet.com, so I got it.

But the installation cannot proceed since I don't have Visual Studio 2008 installed, so I stuck.

 

I don't want to re-install the full XE4 because I've got so much IDE plugins and custom settings. Any advise? Thanks.

did try install just only the "Microsoft C++ Redistributable and Visual Studio 2008"  for Win7?

See attached, I think I have all the VC 2008, 2010, 2012, 2013 and 2017 redistributables...

Thanks for the info, tried both h2reg and h2viewer, both give me the following error:

MS Help 2.x runtime files are not installed on this PC.

I wish Delphi kept using the good old CHM or .hlp help file formats...

They've already gone back to them. On the recommendation of MS itself
