I am running a fully-uddated version of Windows 11 Professional Version 10.0.22000 Build 22000, and when I try to view a ".chm" file in 'HTML Help Workshop' by clicking on the button with glasses image, or I click on the .chm file in Windows Explorer, an application runs and display the text:
"Make sure the web address //ieframe.dll/dnserrordiagoff.htm# is correct"
This is the same issue described at the link further below, although I don't know that it is due to the update mentioned.
Applying recent Windows updates appears to prevent HTML help files from displaying correctly when accessed remotely (UNC & network drive) RRS feed

I have looked at the solution for Windows 7 on this website proposed at the following link.
Cannot Open CHM Files

I wish to put am MFC applicaton on the Windows store. It was a lot of work creating it. It has an executable and six DLLs. I wanted to include help, but I obviousy won't make security changes to user's systems during the install of my program.
I'm not sure what to do.
I also see a similar request here from 2011.
Do I have to drop HTML Help, and if so, what is the alternative?
Help .chm files not opening

Note, the HTMP Help inside of HTML Workshop does work.
Any fix where I have to change user's systems innapropriate obviously isn't a solution I can use.
My app is in C++ and uses the MFC Framework. I did not use dotnet. I added dotnet tags because three tags are required, but not other tags were available.
