Launching iTunes in 64 bits mode

I just got my MAC upgraded to OS X Mavericks.
Now I'm trying to open iTunes. I get the error message that iTunes needs to be in 64bits mode to be launched. It tells me to uncheck the box that says to open in 32 bits. This box is not checked. Version of iTunes is 11.1.5.
what should I do next?
Thx

Check your plug-ins.
Usually there's a "32 bit only" plugin (a visualizer most likely) that OS X is reading as loaded when iTunes opens. That causes this error.

Everytime I open my iTunes it says "Running iTunes in 64-bit mode requires Mac OS X 10.7 or later" how do I fix this?

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.

How to put itunes in 64 bit-mode??

I recently downloaded Mavericks and when I try to open itunes on my computer, it states that I have to run it in 64-bit mode. It gives me instructions on how to change my itunes from 32 to 64 bit-mode by going to itunes on Finder, clicking "get info" and unchecking 32 bit-mode, but once I got to the "get info" step, there wasn't an option anywhere to uncheck the 32 bit-mode box!
Is there another way I can update my itunes to 64 bit-mode?? I can't even open my itunes without this message popping up!

Open About This Mac from the Apple Menu. Check that you really are running 10.9.1.
Drag iTunes to your Trash, then download and install again. The link is in the previous post.

i received an error message "iTunes requires 64-bit mode" says to go into my iTunes application and 'uncheck' the 'open in 32-bit mode' checkbox - i went into the application and the box was not checked anyway so why am i getting this prompt? Never happened before. yesterday did the sofware update for maverick.

Thank you for your response, Chris. But I'm afraid I have to disagree. There are native 64 bit versions of iTunes available for OSX and Windows.
In a 64 Bit Windows environment native 64 Bit Applications install the DLL's in a directory called "Program Files" and a directory called "Program Files (x86)" (32 Bit applications only use the ladder).
iTunes 9 is consistent with this behavior - and it identified itself to the system as a 64 bit application (meaning it's process appears without a "*32" tag on it).

Why must I open iTunes in 32-bit mode to play Burn Notice Season 7 episodes on a MacOS 10.8.4 system?

I have an Intel Mac Pro (tower system) running MacOS 10.8.4 with iTunes 11.0.4 (4). Why must I open iTunes 11.0.4 (4) in 32-bit mode to play the latest (as in June 2013) episodes of Burn Notice (Season 7) when PRIOR episodes of Burn Notice (i.e., Season 6 and below) have no problems being played in 64-bit mode? But after I play the Season 7 episode ONCE in 32-bit mode iTunes, I can restart iTunes in 64-bit mode and then play that same episode without a problem? It seems like something in the file is erroneously set in 32-bit mode upon downloading from the iTunes Store that once played in a 32-bit mode iTunes, upgrades it so it can be played in a 64-bit mode iTunes. If I try to play the Season 7 episode in 64-bit mode iTunes without first playing in 32-mode iTunes, I get the dreaded error message, "This movie requires QuickTime, which is not supported by this version of iTunes."

Just got same problem.
#1. There is no Box, under Label or anywher to uncheck or check.
#2. The device I want to use does not have an update driver. What I really need if for the Box to check or uncheck which should be there according to Apple Help.
#3. I tried this, resetting the whole computer's kernal extension by using a Terminal command (although I don't like doing that). It didn't work. sudo systemsetup -setkernelbootarchitecture i386
So I reset it to: sudo systemsetup -setkernelbootarchitecture x86_64
But emphasize, again, I don't like doing SUDO commands in Terminal.
So...Anything else to try?
Thanks for any info that might help.

ITunes requires 64 bit mode after Mavericks update from Snow Leapard 10.6

Responded to Apple Mail invite to update to Mavericks after checking my Mac and OS were compatible. Followed instructions to Mavericks Install and all went smoothly. Unfortunately, ITunes will not load, it's icon bounces a few times but then provides message box: iTunes requires 64 bit mode go to Finder Applications and Get Info and uncheck 32 Bit mode. Well, 32 bit mode is not checked anyway! No restart, reload, or Time Machine restore has rectified the situation. iTunes will not load.
As iTunes is the most valued application on most peoples machines, and provides Apple with a huge income, upgrading to Mavericks is going to be a very costly blunder for Apple sales
unless a solution can be found quickly. I have an iPad and iPhone, neither of which can now link up to the Mac on ITunes.
Update patch for Mavericks please Apple.....asap!!

MyGermanClass is one screwed up website. It no longer exists. The developer says he is in the process of uploading all videos to YouTube. That was in 2011. The last comment on iTunes was in 2006, 8 years ago. I think we can safely say this is not a valid example.
Be that as it may there is no work around nor should there be. Time marches on and your example is woefully outdated and was produced by totally incompetent people who have chosen to stay in the past.

ITunes requires 64 bit mode.

I can not access itunes on my macbook pro. Receive a message stating to go to FINDER, GET INFO, and uncheck the 32 bit mode box. I cannot uncheck the 32bit box - because it is not checked. How do I acces itunes ?

Have you tried checking then unchecking it? If that doesn't work (I doubt it will) try reinstalling iTunes.

Please help me??
Can not open Itunes as had a software update and will not let me open. Is asking for me to open in 32 bit mode, follwoed intructions and to no avail.

Install the most recent version of iTunes, 10.4.1, from support.apple.com/downloads/. Or select the iTunes application. Press COMMAND-I to open the Get Info window. In the upper panel you should see a checkbox labeled, "Open in 32-bit mode." Check the box.

ITunes x64 runs in 32-bit-mode?

Hi,
ive installed iTunes v8.0.035 on my MS Windows Vista x64 Machine.
After starting the iTunes application, i took a look at the Windows Vista Task Manager.
At the tab "processes" is listed: "itunes.exe *32"
That means IMHO that the program runs in 32-bit-mode.
Any idea whats the problem, and how to start iTunes in 64-bit-mode?
thank you!

Same question here. I thought perhaps I downloaded the wrong file, but I clearly checked "Vista 64-bit" and downloaded the file I downloaded was "iTunes80164Setup.exe", and yet, iTunes 64-bit appears to continue to run as a 32-bit program.
I know that Vista has a compatibility mode or something. Could it be that Windows itself is mis-recognizing iTunes 64-bit?

No "Open in 32-bit mode" check box in iTunes "Get info"

When I try to run iTunes the error message. "To run iTunes in 64-bit mode, select the iTunes application in the Finder, choose the “Get Info” command in the File menu, and uncheck the “Open in 32-bit mode” checkbox in the iTunes Info window."
I have just updated to 10.9

After long phone call with apple support the thing that seemed to work was:
make a new user.
Copying the itunes app from the new user’s Application folder to the shared folder.
Then open up your old user account and copy it over the old itunes app.
hope it works for you too

ITunes - 32 bit mode - with old video, in Yosemite?

Hi,
I'm considering upgrading to Mac OS X Yosemite from OS X 10.7.5. However, I have read online that Yosemite only supports 64 bit mode applications.
I have a large video library of iTunes content, which I began purchasing about 10 years ago. When I upgraded another Mac I own to 10.8 (from 10.6), I found that I could no longer play some of my iTunes video files. On example is Stargate SG:1. Upon attempting to play this video and others, an error message would appear reporting that "This movie requires QuickTime, which is not supported by this version of iTunes."
The solution to this problem (as described here: iTunes for Mac: Older media files may require iTunes to reopen in 32-bit mode - Apple Support) was to check the info box in iTunes to select operation in 32 bit mode. This solved the issue- I was able to play the old video files.
Now I'm considering upgrading to Yosemite. However-- if this option is no longer available (running iTunes in 32 bit mode) will I still be able to play the older video files in the update version of iTunes and Yosemite?
Thanks

Hello there, macdev3456.
I definitely commend you for looking into the compatibility of Yosemite with the needs of your content before upgrading. It seem you are already familiar with the article that references the way to address playing content that requires 32-bit mode in iTunes 12 and OS X 10.10. These steps are still relevant in all current versions:
iTunes for Mac: Older media files may require iTunes to reopen in 32-bit mode - Apple Support
iTunes 10.4 or later on OS X Lion opens by default in 64-bit mode. However, some older media files in your iTunes library may still rely on QuickTime to play, and QuickTime only runs in 32-bit mode. In order to play media that encounters this issue, you will need to open iTunes in 32-bit mode first:
In iTunes, choose Quit iTunes from the iTunes menu.
From the Finder, choose Applications from the Go menu.
Locate iTunes in the window that opens.
Click the iTunes icon to select it. Then, choose File > Get Info.
Enable the option to "Open in 32-bit mode."
Reopen iTunes.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

How can I get my installed plugins to show up in Logic after ive installed the plugin discs? ive tried changing the bit mode. it STILL doesn't work.???

I tried installing a program but when i open logic and scan the audio units, it doesnt come up. Even if i change the bit mode, it still doesnt show up. I even tried restarting my machine..Can anyone help me or give me some ideas.
i just wanna get this plugin to work.

Have you confirmed that the plug-in installed to one of the locations where Logic might find it? Most plug-ins go to /Library/Audio/Plug-ins/Components. Some (rarely) install to ~/Library/Audio/Plug-ins/Components (where "~" is your user folder). Look in both locations and see if the plug-in is actually there.
When installing plug-ins, if you are offered options as to what format to install, be sure to include Audio Units. Logic will not see other formats like VST, RTAS, AAX, TDM, etc. If you use other software that recognizes those formats, it's fine to install them too, just be sure you don't deselect Audio Units.
Finally, if you're sure the plug-in is installed to the right place, open the Audio Units Manager in Logic and check to see if the plug-in passed validation. Go to the main menu and choose Logic Pro > Preferences > Audio Units Manager. Check to see if your plug-in is listed there. If there's not a check mark next to it in the "Logic" column, that means it failed validation. If so, the "Compatibilty" column will tell you why. Keep in mind that if the AU is 32-bit, you have to launch Logic in 32-bit mode to see it here. Likewise, 64-bit plug-ins show up in the manager in 64-bit mode.

Command-Key etc to start an App in 32-bit mode?

Is there some sort of Command-Key etc to start an App in 32-bit mode, without having to go to "Get Info" ?
I have a Canoscan scanner which only runs in Photoshop under 32-bit mode. It would be nice to be able to launch PS into 32-bit mode when I need to, without going to Get Info.

Hi,
This AppleScript script doesn't change anything in (Get info), but launch the application in 32-bit mode.
property appName : missing value
property tpath : missing value
if appName is missing value then
      tell application "Finder"
            set appName to text 1 thru -5 of (get name of (application file id "com.adobe.Photoshop"))
            (application file id "com.adobe.Photoshop") as text
      end tell
      set tpath to quoted form of (POSIX path of (the result & ":Contents:MacOS:" & appName))
end if
get running of application appName
if the result then
      quit application appName
      tell application "System Events" to repeat while exists process appName
            delay 1
      end repeat
end if
do shell script "arch -i386 " & tpath & " > /dev/null 2>&1 &" -- launch (32-bit mode)
delay 1.5
activate application appName
Quit the application and restart to run in 64-bit mode.
To have a keyboard shortcut to run this script: you have some solutions
First solution: Make a service with Automator.
Second solution: There are some third party utilities that launches script, and you can set a keyboard shortcut.

Gaslight could not open in 64 bit mode

Since upgrading to Lion everytime I open iTunes I get this message. There's really no other information other than a check box saying don't show this again and a suggestion to try opening iTunes in 32 bit mode, neither of which I really care to do.
I can't find much information about what "gaslight" is. I think it may be the visualizer that comes with iTunes.

Wrong folder. You need to be looking in the iTunes Plug-ins folder in your user's home folder. The Library folder is hidden in Lion now, so you'll need to use the Go menu -> Go to Folder command in Finder and use the following path:
/Volumes/[name of your hard drive]/Users/[your user shortname]/Library/
Then look in the iTunes/iTunes Plug-ins folder there.
Regards.
