HT1926 Unable to install itunes on windows 7. error code 2721.

I am trying to install iTunes on my PC but keep receiving the error message 2721 and then the installer quits.

It is an ongoing issue with installing iTunes 7 on Windows.
What often solve the problem is running installer as Administrator
and the opening iTunes as Administrator
Right click on the installer and "Run As Administrator"
Also as b noir mentioned - can you post the error message?
This would help.

  • Can't install iTunes on Windows 7 - error code 2329

    I just installed Windows 7 on my computer and now am trying to re-install iTunes...I uninstalled it before upgrading from Vista to 7 because a compativbility scan said that iTunes could cause problems with the installation of Windows 7
    Now, after saving and running the iTunes installer on my computer, I get error code 2329 while trying to install. I believe this happens when it is trying to initially install Quicktime, which I actually still have installed on my computer...
    I have tried uninstalling Quicktime, but I get the same error code during that process
    I have also tried installing iTunes by going to the Apple Software Update instead of saving and running the file from the internet, but it fails also....
    Please help!

    Now, after saving and running the iTunes installer on my computer, I get error code 2329 while trying to install. I believe this happens when it is trying to initially install Quicktime, which I actually still have installed on my computer...
    The 2329 appears to be associated with file/disk damage, lora (much like the more-common 2330).
    So we should try first running a disk check over the drive your QuickTime program files are stored on. For instructions, see:
    [How to use CHKDSK (Check Disk)|http://www.w7forums.com/use-chkdsk-check-disk-t448.html]
    Try checking both boxes. The scan should take quite a while. If the scan aborts fairly quickly (even if you do it on Start-up), try rebooting the PC, disconnecting from your network and/or the internet, and disabling all security software on the PC (firewall/antivirus/antispyware) prior to doing the disk check. (Real-Time scans of your drive by your security software can interfere with disk checks.)
    Reenable all your security software prior to reconnecting to your network and/or the internet.
    Does the disk check find/repair any damage? If so, are you able to do the iTunes install afterwards?

  • Unable to install iTunes ,it said about error code 2869.

    I have a problem with my iTunes reinstallration. I try to remove the old one ,but it said about the error code 2869.

    That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
    XP instructions in the following document: How to perform disk error checking in Windows XP
    Vista instructions in the following document: Check your hard disk for errors
    Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
    Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
    Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?

    These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.
    Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?
    If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? (For example, 8007000B.)

    Why not?  Should we guess at the issue or do you plan to provide details so that others can offer suggestions/solutions?

  • Unable to install ituns on windows 7 64 missing .dll file

    Unable to install ituns on windows 7 64. Installer states missing .dll file.

    Here is a solution that worked for a user who also had a problem with iTunes Software Support. This thread was for a win32 version, but Maybe this is the problem for both of you?:
    IT appears that AppleApplicationSupport.msi, is not opening and installing properly.
    Download and SAVE iTunesSetup.exe, where you can find it.
    Then:
    1. Download and install WinRAR.
    2. Right-click the iTunesSetup.exe icon and choose "Open with WinRAR".
    3. Once the EXE is opened in WinRAR, double-click AppleApplicationSupport.msi and when the installer window is open choose "Repair".
    4. Done! You can now run iTunes normally.
    Here is a link to that fairly lengthy thread.. http://discussions.info.apple.com/thread.jspa?threadID=2151777&tstart=-1

  • Unable to install Itunes in Windows XP

    I am unable to Install Itunes oin Windows xp professional SP2, it gives below error: Let me know how to get it installed

    OK, there is still not much to go there.
    I assume you are using 32 bit XP Pro, iTunes will not install on 64 bit XP but you should get a different error.
    Lets try installing the components of iTunes separately.
    Download the iTunes installer and save it in your downloads folder.
    The files will be either itunessetup.exe or itunes64setup.exe for a 64 bit system.
    Open notepad and copy the following 3 lines into it.
    md temp
    itunes64setup /extract temp
    pause
    Remove 64 for 32 bit itunes.
    Save the file as extract.bat into the same folder that contains the itunes installer.
    Open the downloads folder and you should find the extract file that you saved. Double click on it and a black window will open telling you what it is doing. When its finished, press any key to continue.
    You should find that a folder called temp has been created containing all the itunes msi files.
    Install by double clicking on them  in this order:
    Apple Application Support
    Bonjour
    Apple Mobile Device Support
    Apple Software Update
    iTunes
    Make a note of any error messages and which component it relates to.
    Also use the Windows Event viewer to see if there are error messages at the time you attempted the installs.
    The following article gives information about using the Event Viewer:

  • Unable to install Itunes on Windows 8

    Unable to install Itunes on Windows 8.
    It states Errors occured during installation. Your system has not been modified, and does not fully down load.
    I have tried :-
    Uninstall Itunes and then reinstall
    Uninstalled Itunes then connect Iphone to computer and tried to source relevant Itunes package.
    ininstalled Itunes then tried to install a later version
    Even tried an Itunes 64 bit installer then tried to download Itunes.
    All the above have been unsucessful. I have a 64 bit operationg system, x64 based processer laptop computer.
    I have spoken to the staff at apple store who were all really nice but could not offer any help unless I had an apple computer.
    Please help as I have two Iphones and an Ipad which are limited without Itunes.

    See Troubleshooting issues with iTunes for Windows updates.
    If you still have problems installing iTunes download and install 7-Zip (free) and a fresh copy of the current installer from https://www.apple.com/itunes/download/ or use these direct links (which will go out of date at some point):
    iTunes 11.1.5 for Windows (32-bit) - iTunesSetup.exe (2014-02-25)
    iTunes 11.1.5 for Windows (64-bit) - iTunes64Setup.exe (2014-02-25)
    Then unpack the installer into its components using 7-Zip and install them individually in alphabetical order (don't try to install SetupAdmin.exe or iCloud.msi). If any of the components still fail to install you may get more useful error messages as to why not.

  • I can't install itunes for windows get error message 5

    i can't install itunes for windows get error message 5

    I've been having the same issues for the past year and a half. I've spent 6-8months trying to figure it out. Went to various Itunes stores with pictures on my Iphone per each step so I could relay all information that I'd come across and the personnel were less than helpful, after conversations that would sometimes last an hour between myself, employees and managers they always came back to "simply uninstall then reinstall" when I told them for the thousanth time that I've done that multiple times and my errors are happening while trying to reinstall it they act stumped and say "well then I'm not sure, I'll give you a call if I figure it out" and disappear. I've been very disatisfied at the lack of support from Apple and if Android to piece together a reletively reliable phone I'd switch to them in a heartbeat. I'll follow this question incase someone can answer this, but I don't have much faith.
    BTW, wifey has Windows 7 running on the laptop and my phone syncs just fine to that and no trouble with itunes, just mine (desktop).

    Try updating your iTunes using an iTunesSetup.exe (or iTunes64Setup.exe) installer file downloaded from the Apple website:

  • I am still unable to install itunes in Windows Vista

    I have tried to run Fix it 4 times now after doing other things suggested in the Apple community and I am still unable to install itunes. Do you have any other ideas?
    I've been uninstalling/reinstalling and using CCcleaner, sfcscannow and nothing seems to correct error msg 2- corrupt files found/unable to fix.  Now what??????
    I am using windows Vista.  I NEED help!

    nothing seems to correct error msg 2
    With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
    Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
    http://www.apple.com/itunes/download/
    Download and install the free trial version of WinRAR:
    http://www.rarlab.com/download.htm
    Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
    Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
    Does it install properly for you?
    If instead you get an error message during the install, let us know what it says. (Precise text, please.)
