--- Comment #7 from somewise@gmx.de --- Works for me. Before I have noticed that the Apple Application Support dlls are put in '/Program Files (x86)/Common Files' instead of 'Program Files/Common Files/' on my 64 bit Windows 10. So I extracted AppleApplicationSupport64.msi from iTunes6464Setup.exe. It is a 32 bit version in there, too, but I used the 64 bit one.
msiexec -i AppleApplicationSupport64.msi fixme:ntdll:NtLockFile I/O completion on lock not implemented yet...
---and the setup even propose 'Program Files (x86)/Common Files'. Do you need a trace?
The unusable interface looks the same like the 32 bit one. Native gdiplus fixes this. But using winetricks gdiplus for 64 bit I get the same 'Error 7 (Windows error 126)':
err:module:import_dll Library gdiplus.dll...
