64-bit iTunes running in 32 bit mode?

I installed the 64bit version of iTunes ont he 64bit Windows 7 Beta. It works fine, but taskmaster tells me that itunes.exe is a 32 bit program. Is the 64 bit iTunes just an installer or is it supposed to actually run in 64 bits?

My understanding is that the iTunes executable is still 32-bit.

Fallout75, good catch on the eXo plugin. To remove it, in the Finder click "Go" on the menu bar and pull down to "Go to Folder" and then type ~/Library/iTunes/iTunes Plug-ins
When that Finder window opens, you should see an "eXo" subdirectory. Just delete that "eXo" folder and iTunes should start without the error.

After updating to Mavericks I can't open iTunes. I keep getting a popup telling me to unclick "run in 32- bit mode" in iTunes info. I have done that several times and rebooted. Everything else seems to be working fine.

After updating to Mavericks, I can't open iTunes. I keep getting a pop up telling me iTunes needs to run in 64-bit mode. After following directions several times to go to Finder, iTunes, Get info and "unclick 32-bit mode" it still won't work and i keep getting the smae pop up window. I've rebooted several times also.

What version of iTunes do you have? The current version of iTunes for Mavericks is 11.1.5 and the default mode is 64 bit. If "Open in 32 bit mode" is checked and you cannot uncheck it are you logged on using an account with administrative priveleges?

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.

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?

Why does the iTunes 64 installer install into the Program Files (x86) directory and run in 32 bit mode?

I have just installed this and even tried to manually get it to install in the "Program Files" directory. Programs installed into the "Program Files (x86)" directories are 32 bit apps. This is where the iTunes64Setup file installs to. Is this intended? If so, why call it iTunes 64 bit ? It is compatible in this mode, but iTunes actually running in 64 bit mode could drastically improve performance and processing of large libraries.
Please advise if this is a known issue or if iTunes 64 bit even exists.

The 64-bit version of iTunes is a mixture of 64-bit and 32-bit componentry. You'll also notice on your PC that some of the componentry for iTunes itself is installing in the iTunes folder in the Program files directory (such as the miniplayer). The GEAR drivers used for burning and importing are 64-bit. The iPod service is 64-bit. AMDS is 64-bit. Bonjour is partially 64-bit.
It's normal to see the itunes.exe process running as 32-bit on a 64-bit system.

Itunes is running in 64-bit mode and will not let me switch to 32- bit mode

I guess 64-bit mode requires MAC OS X 10.7 and I only have 10.6.8 so somehow i need to switch back to 32-bit mode and the instructions it gives me to do so don't make any sense. help!

At Mike Johnson12's suggestion I posted my problem separately at https://discussions.apple.com/message/15801854#15801854 . The only response I have received there so far is from another person who has experienced the same problem you & I have. That makes at least 3 of us. Please feel free to hijack my post there if you think it might help!

How do I get iTunes to open in 32-bit mode if I don't have a Mac, just a PC

I am trying to play a tv show on my PC that I bought on iTunes and it says I don't have the Quicktime, or something like that. So I downloaded a new Quicktime and it still says that. So I clicked on more info and it took me to an Apple page showing how to get iTunes to open in 32-bit mode from a Mac. I have a PC and I need to know how to get iTunes to run in 32-bit mode

You can use "History > Restore Previous Session" to get those page back.
Are you restarting this way?
# Close Firefox
# Open the Applications folder in Finder
# Right click or control-click the Firefox.app icon
# Select "Get Info"
# Select "Open in 32-bit mode"
# Close the "Firefox Info" window
# Restart Firefox

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.

Whitecap could not load in 64 bit mode error when opening iTunes. What do I do?

Upgraded to Lion recently. Opened iTunes and got a "Whitecap could not load in 64 bit mode". Tried to sync my iphone a few times but iTunes crashed. Managed to fix the problem by making iTunes run in 32bit mode only. My version of iTunes is 10.4 (80). Something is wrong here though as I thought this version is a 64 bit version.

there's a system library and each user has a library. have you ever installed something and the installer asked you if you wanted to install it for all users? it would put that in the system library. the way you installed this whitecap plugin for itunes as your user, my user can still log onto the same machine and not be affected by it. why did they hide the user's library folder? i guess they felt you wouldn't need to go in there and mess things up on accident. the other way to get to these "hidden" folders is by going to finder and clicking the Go menu then Go To Folder (Shift + Command + G). it's even tab completable, which is nice =)

ITunes will only open in 64 Bit Mode from Dock since Restore

I have only ONE big problem since doing a restore from my Time Machine backup-up for for Late 2009 iMac 27". For some reason I can only get iTunes to open in 64 bit mode if I put an icon on the dock???? It opens in 32 bit mode which is selected in the Get Info - Command+I if I open it from the Finder (which is my preference due to my many 32 bit Visualizers....) but if I put a shorcut icon on the dock REGARDLESS of what my settinigs are in the finder it Always opens in 64 bit mode and tells me my visualizers can not be loaded... Which I am well aware of!   What I don't understand is why this has just happened since reformating and restoring from a time machine backup???? Everything else... at this point appears to be working just fine.   BUT if I open iTunes from the dock... 64 bit mode no questions asked.... opened from Applications in the finder and it grabs my 32 bit mode Prefs?    This is really irritating. I have dumped caches, re-downloaded and installed iTunes.   Not sure what else to do???   Why is this ONLY happeningn if I put an iTunes link on the Dock?    Any help would be VERY MUCH appreciated.   Thanks.

Frank -
Here's the latest. I did the old standby of creating another Admin Account and the behaviour does not occur when logged into that account. So it appears that the restore somehow screwed up settings on my current account. I have indeed checked and there is no other copy of iTunes on my computer except for the DLoaded version of iTunes10.6 where I downloaded and tried to the re-install thing.
Of course still haven't heard back from Apple but I really wasn't expecting too this early. I guess that my next step is to transfer to the user/shared folder and change permissions on each and every folder/preference and file to the new Admin account... until I find out which setting is causing the problem.   To so this is a pain in 'arse' would be an understatement.
Also found out that Preferences has the same behavior as iTunes.   64 bit ALWAYS unless checked during that specific login and NOT started from the dock....   Strange though... both seem to hold the 32 bit (for the session) if run from 'recent', the Apple Menu, or the Finder???   As Alice would say "Curiouser and Curiouser"
My suggestion to ANYONE converting to LION (after this episode) is to back up and do a CLEAN install.   Obviously something from Leopard and Snow Leopard doesn't really like Lion that much.
I have been using computers since 1981 and Apples since OS 8 ... even had few dificulties with the OS X beta, but this one has me befuddled and somewhat irritated. I have thousands of dollars worth of software that I really don't want to have to re-install, re-register, but that may be the only viable option at this point.

Aperture 3.1 - OS 10.6 Conflict when trying to run in 32 bit mode?

Hi All,
I'm looking for advice on running Aperture in 32 bit mode to use plugins. I already posted a question in the Aperture forum, but was advised to post it here as the issue may be with the OS. I am running Snow Leopard and can't seem to force Aperture into the 32 bit mode.
I have checked the box "Open in 32 bit mode" in the Get info menu in Finder, but when I launch Aperture and try to use a 32 bit plugin, it tells me that I need to reopen it in 32 bit mode or contact the developer.
I'm running Aperture 3.1. The 32 bit plugins I'm trying to use are:
Sharpener Pro
Color Efex Pro
Dfine 2.0
Hydra HDR
Any ideas on how I can get around it would be hugely appreciated!
Thanks,
Svetlana

More RAM than the 4GB per application a 32-bit OS offers would be of no help. iTunes uses a flat-file database, basically just a text file, and that's the main reason why it performs poorly when you get a very large library. More RAM would not help since even a very large library file can easily fit into a 32-bit address space, so more RAM allocated to the program would not improve matters.
Regards.

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.

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
