Again, if command line is not your thing, try the foobar2000 option. But I have not tried this. The following is what I would try:

1) Install Foobar2000
2) Download and install "foobar2000 Free Encoder Pack"
https://www.foobar2000.org/encoderpack
3) Place the 10 needed Apple Application Support files in the same directory as Foobar2000 QAAC.exe
Does QAAC work in Foobar2000 now? YES-> Done!

No:
Delete them
Create a directory here:
C:\Program Files\Common Files\Apple\Apple Application Support\
Add the 10 files here:

C:\Program Files\Common Files\Apple\Apple Application Support\ASL.dll
C:\Program Files\Common Files\Apple\Apple Application Support\CoreAudioToolbox.dll
C:\Program Files\Common Files\Apple\Apple Application Support\CoreFoundation.dll
C:\Program Files\Common Files\Apple\Apple Application Support\icudt55.dll
C:\Program Files\Common Files\Apple\Apple Application Support\libdispatch.dll
C:\Program Files\Common Files\Apple\Apple Application Support\libicuin.dll
C:\Program Files\Common Files\Apple\Apple Application Support\libicuuc.dll
C:\Program Files\Common Files\Apple\Apple Application Support\objc.dll
C:\Program Files\Common Files\Apple\Apple Application Support\msvcp100.dll
C:\Program Files\Common Files\Apple\Apple Application Support\msvcr100.dll
Does QAAC work in Foobar2000 now? YES-> Done!

No:
Create 2 more directories and put copies of the 10 files in them:

C:\Program Files\Common Files\Apple\Apple Application Support\CoreFoundation.resources\
C:\Program Files\Common Files\Apple\Apple Application Support\CoreMedia.resources\
Does QAAC work in Foobar2000 now? YES-> Done!

No:
I don't know Sorry.
You'll have to research (Hydrogenaudio.com is the best place to start), or just install
AppleApplicationSupport.msi extracted from an itunes xx.xx.exe package with
7-Zip (Recommended)
https://ia600305.us.archive.org/6/items/Complete_iTunes_Archive/iTunes for Windows/
Last XP Version: iTunes 12.1.2.27
https://discussions.apple.com/thread/7113255?sortBy=rank
(Then overwrite the 10 files from https://github.com/AnimMouse/QTFiles/releases that I already mentioned. (Extracted from the version 12.9.2.6 of iTunes)
And get that copy of CoreAudioToolbox v7.9.7.9 for CBR encoding that I mentioned.
