I am trying to play a TV show purchased recently from the iTunes store and get the following error message:


"This movie requires Quicktime, which is not supported by this version of iTunes."


This is the latest version of iTunes 10.6, and I tried reinstalling it with no luck.  My Mini never had a problem before iTunes 10.6 and it meets all the system requirements for iTunes 10.6.


Why would the iTunes store sell a TV show that requires Quicktime while the latest version of iTunes doesn't support Quicktime?

Mac mini, Mac OS X (10.7.3)

    I'm going to assume that this is a low-memory problem and have ordered an 8 GB memory upgrade for both my minis.  (Both have had serious iTunes problems since 10.6 was installed).  I'll report back after the upgrade.

    Installed 8 GB memory but iTunes is still not working.  Installed iTunes 10.6.1 - no help.  Also did a clean reinstall of the OS - no help.  Time to go back to the Genius Bar (with both minis).

    Third visit to Genius Bar.  After trying several combinations of DVI/HDMI adaptors and HDMI cables, we saw nothing to indicate a cable/adapter problem.


    The Genius then found




    which says that iTunes, which ordinarily starts in 64-bit mode, needs to run in 32-bit mode because Quicktime is only 32 bit.  This explains the error message seen earlier: "This movie requires Quicktime, which is not supported by this version of iTunes."  ("Explains" is being overly generous.  Had the error message been more exact I could have saved 4 weeks of work and 3 trips to the Apple Store.)


    TV shows are now playing reliably.

    In my case, it's all my home movies (nothing purchased) that fell victim to the iTune/QuickTime problem. Please, if the soltution is to change iTunes from 64 bit to 32 bit, how is that done? "Help" offers no hint. Thanks.


    Oops! Sorry, I should have read the bulletin from the Genius Bar guy which you were nice enought to include. My impatience! Thanks for solving this problem for all of us.

    This link has pretty good instructions.  If it doesn't work for you, let us know.

    I tried the 32-bit trick and the QuickTime error went away, but now when I try to preview music videos or watch movie trailers, the movie window opens but nothing plays. It is just a dead black window. I checked the Console and I saw an iTunes error, "unexpected connection closure". Not sure what that means. I checked my QuickTime and saw that it too has a 32-bit option which made me think that both iTunes and QuickTime normall run in 64-bit mode so perhaps my issue is different. Any thoughts? Thanks.

    I did not change the Quicktime 32/64 bit setting but it did not seem necessary.  I suppose you could try that and see if it addresses your problem with previewing music videos and movie trailers.

    Problem mysteriously went away this morning. Both iTunes and Quicktime are in 64-bit mode.

    This option may be more inconvenient but works:


    Right click the movie you want to watch within iTunes


    Select show in finder from the right click menu that appears


    (Finder will open - displaying the file)


    Double click on file


    (Quicktime will open)


    Play your movie

    This doesn't work on Mountain Lion and, what surprise me the most, I can't open Apple Developer movies with iTunes and that is the only way for some movies to be played.

    Is there any other ideas for this problem?
