--- Comment #9 from winetaste@gmx.net --- I have investigated, before fixing there are almost only 32bit DLLs in "Program Files (x86)/Common Files/Apple/Apple Application Support", but CoreAudioToolbox.dll is 64 bit.
Running extracted AppleApplicationSupport64.msi with clean prefix there are only 64 bit DLLs and running AppleApplicationSupport.msi only 32 bit DLLs.
Maybe first 64 bit MSI is executed and then the 32 bit one that overrides the DLLs, because 'Program Files (x86)/Common Files' is proposed for 64 bit version, too? Though on Windows just the 64 bit version seems to be executed...
