I just double-checked the 2022 beta I still have installed, and it has the chm offline help (which looks to be for 2021). So NI have snuck this into 2022 Q3, with zero mention of it in the release notes. Anything else you've slipped in without telling us, NI?
I thought maybe NI dropped the old chm to satisfy Windows 11 support, but Win11 supposedly still supports opening and viewing chm files. Accepting that chm is an outdated format and needs replacement, the alternative should still be available offline for many of the reasons already stated.
The new online help is absolute garbage. I hate everything about it. It's obvious little thought has been given to actually using it - NI are just ticking requirements checkboxes. There is the offline help viewer, but I can't for the life of me find any offline help to download anymore (it was easy to find during the NXG era). Now it's just auto generated PDFs that don't seem to generate half the time.
It's become increasingly clear NI do not understand their users, or simply do not care.
