Microsoft Document Viewer is a help viewer deployed with several Microsoft
applications (MSDN, Visual Studio, driver development kits, etc.).

Version 7 works very well, but both versions 8 (from Visual Studio 2005) and 9
(from WDK) are completely unable to display help pages. In the left side bar,
you can browse the tree of help topics, and search the help index, but when you
click on a topic, the region of the window where the contents of the help topic
are meant to be displayed just stays blank.

To test version 8, "winetricks vc2005express", and then start Visual Studio and
click on "Help" -> "Contents".

To test version 9, "winetricks mfc42 dotnet20", then run the WDK binary linked
here. After installation, from your $WINEPREFIX/drive_c, run it with something
like:

wine start "users/`whoami`/AppData/Roaming/Microsoft/Windows/Start
Menu/Programs/Windows Driver Kits Documentation/WDK 6001.080214/Help/WDK
Documentation.lnk"

Trying native DLLs for these components had no effect:
msxml3
msxml4
msxml6
ie8
shdocvw

It's probably not a regression - it was broken this way at least as early as
2019 in bug 12406.
