Apple Takes iTunes 10.4 to 64-Bit for Mac/Windows

| Product News

iTunesApple released iTunes 10.4 Wednesday, and the number one change in the new release is that the software is now 64-bit in Lion and 64-bit Windows Vista and Windows 7. Other enhancements include support for Lion’s full-screen mode.

Apple’s patch notes:

What’s new in iTunes 10.4

iTunes 10.4 is now designed for OS X Lion. You can now use iTunes with OS X Lion’s new Full-Screen App capability, which allows you to use iTunes and other without distractions. Navigate between your full-screen apps with a simple gesture.

iTunes is now a 64-bit Cocoa application on OS X Lion and includes a number of important stability and performance improvements. Some iTunes plug-ins may no longer be compatible with this version of iTunes. Please contact the plug-in developer for an updated plug-in compatible with iTunes 10.4.


iTunes 10.4 provides a number of important stability and performance improvements.

The patch notes for the Windows version stipulate that the 64-bit version only works with 64-bit versions of Windows Vista and Windows 7, and that 64-bit Windows XP is not supported. Windows users can update through the Apple Updater utility on their PC or through Apple’s Download site (32-bit users should use the main iTunes 10.4 KnowledgeBase article while 64-bit users should use the dedicated KnowledgeBase article for the 64-bit version).

Mac users can update through Software Update (64.1MB download), or through the standalone installer from the update’s KnowledgeBase article (90.23MB).

Actually, 64 bit iTunes for Windows has been available for a couple years. Unlike the new 64 bit Mac version, the 64 & 32 bit Windows versions have been separate downloads.

But it was a 32-bit application.  If you notice, it installs to the Program Files (x86) folder.

Cisco VPN does the same thing.  The drivers may be 64-bit, but it doesn’t mean that the program was.  It looks like they recompiled the EXE to be for 64-bit processors.  Hopefully this means that I can actually watch rented movies reliably on it on my notebook computer now.  Performance was horrible before.
