When I try to install iTunes, I get an error message that Apple Application Support is required.

When I try to install iTunes on my Windows 7 PC, I get an error message that Apple application support is needed. What do I need to do?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if Apple Application Support won't install normally. You could try this approach first.

Okay. We'll try a different utility.
(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

HT1349 I have installed and uninstalled iTunes on multiple occasions, but keep getting the error message that "Apple Application Support is required to run iTunes ..... Error 2 (Windows Error 2)". Can't find any useful solution. Can anyone help? Pleeee

I have instlled and uninstalled iTunes on multiple occasions but iTunes fails to start with message "Apple Application support is required to run iTunes .......... Error 2 (Windows error 2)". Most most frustrating. Can anyone help, pleeeeeeease!!

iTunes "Apple Application Support is required... Error 2" and possible fix.
Hi Redgilly (and others).
I just resolved this on Win Vista (should apply equally for Win7 too). Please uninstall iTunes before proceeding though. I'll walk you through the process I followed, if you like you can jump straight to the Solution section.
Problems:
The initial error during the installation of iTunes was:
An error occurred during the installation of assembly 'Microsoft.VC80.CRT,version="8.0.50727.4053",type="win32",publicKeyToken='1fc8b 3b9a1e18e3b",processorarchitecture="x86". Please refer to Help and Support for more information. HRESULT:0x8007054F
The error (after installing iTunes) when trying to run iTunes was:
Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again. Error 2 (Windows error 2).
After trying various fixes around the forums I came across this MSKB article, which relates to the first installation error:
http://support.microsoft.com/kb/2688946
This lead me to trying to install MS Visual C++ but I received the following error trying to install that:
Error 1935.An error occurred during the installation of assembly ‘Microsoft.VC80.ATL,type=”win32”,version=”8.0.50727.762”,publicKeyToken=”1fc8b3 b9a1e18e3b”,processorArchitecture=”amd64”’. Please refer to Help and Support for more information. HRESULT: 0x80070BC9. Assembly interface: IassemblyCacheItem, function: Commit, component: {837BF1EB-D770-94EB-A01F-C8B3B9A1E18E}
Note: The installation of VC++ rolls back when it fails.
Solution:
Through this error I found this MSKB article:
http://support.microsoft.com/kb/946414
The Automated MS "Fix It" msi package didn’t work.
Note: Please backup your registry first (see the above MSKB article for instructions).
I opened the registry and (as instructed in the MSKB article) deleted the following keys:
HKEY_LOCAL_MACHINE\COMPONENTS\
PendingXmlIdentifier
NextQueueEntryIndex
AdvancedInstallersNeedResolving
Reboot and reinstall iTunes.
I hope this helps.

When I attempt to install iTunes I get an error message about Apple Support Service needed to run iTunes.

What is Apple Support Services and where can I get it so I might download iTunes?

Apple Support Services
What's the precise text of the message, please? (There's an Apple Mobile Device Service, and Apple Mobile Device Support, and Apple Application Support ... so it's not clear what you might be having trouble with at the moment.)

When I try to open iTunes, I get this error message: Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item. I get a different error message if I try to uninstall it.

When I try to open iTunes, I get this error message: "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I've been able to uninstall all Apple products except iTunes as I get this error message: "The Installer has insufficent privileges to modify this file: C:\Program Files\i Tunes\Acknowledgments.rtf." I've had the iTunes on my laptop for a year and a half with no problems until now.

Any suggestions please?

Uninstall your existing copy of iTunes. Delete any copies of the iTunesSetup.exe (or iTunes64Setup.exe) installer files from your downloads areas for your web browsers and download a fresh copy of the iTunes installer from the Apple website:
http://www.apple.com/itunes/download/
(The current build of the 11.1.4.62 installer was changed a few days ago, which fixed the bulk of the reports of MSVCR80.dll/R6034/APSDaemon.exe/Error-7/AMDS-could-not-start trouble ... but the build number on the installer was not changed. So we're trying to make sure you do the reinstall using a "new good" 11.1.4.62 installer instead of an "old bad".)
Does the install with the new copy of the installer go through properly? If so, does that clear up the error message?
If you still have the same error messages cropping up, then try the procedures from the following user tip:
