For AAC encoding, qaac requires non-free library files from Apple.

1. Download iTunes64Setup.exe from:

https://www.apple.com/itunes/download/win64

2. Download makeportable2.cmd from:

https://drive.google.com/drive/folders/196aPmuqmyHZrRQJF6cpDiQ9T4DFYaeET?usp=sharing (Unzip makeportable2.zip)

3. Put iTunes64Setup.exe and makeportable2.cmd in the same folder and run makeportable2.cmd in the Command Prompt.

If successful, QTfiles64 folder will be created containing required libraries.

Put the QTfiles64 folder under the qaac folder in <StaxRip-Folder>\Apps\Audio\qaac.

If you put the files somewhere else, use:

Apps Manager(F9) > Apple Application Support > Tools > Edit Path

The following files are needed:

ASL.dll
CoreAudioToolbox.dll
CoreFoundation.dll
icudt55.dll (or icudt62.dll)
libdispatch.dll
libicuin.dll
libicuuc.dll
objc.dll

The MS VC runtime files are not needed because StaxRip has an All-In-One runtime package included. It's located in:

Apps\Support\VC
