Itunes install error 7 (solution results in errors)

I have the same problem as discussed here: https://discussions.apple.com/thread/2278344?tstart=0
the solution given on there does not work for me. When I try deleting the Apple Application Suport Folder I am told that I do not have permission to do so. I have tried changing the permissions to grant myself permissions for full control (read, write, execute etc) but an error occurs due to ApplePushService.DLL
"An error occured while applying security information to:
C:\Program Files\Common Files\...\AVFoundationCF.Resources***
The access Control list (ACL) structure is invalid"
Please help me as I've been trying to install itunes for months now and have been forced to use alternative software to manage my ipod (Floola). I would like to manage my iphone on my Laptop but it requires me to use itunes!!!!
***I receive the same error message for every file within the folder

Check the hard drive for errors.
Rip it up and start again. (iTunes that is.)

During Itunes install I keep receiving windows error 2 message

I am trying to install itunes on my new HP Pavilion laptop and I keep getting an error message. Windows error 2 message

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 suitable for your PC (there's a 32-bit Windows version and a 64-bit Windows version):
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 so, see if iTunes will launch without the error now.
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

Itunes installing missing MSVR dll and error 7

Hi .
.Just as others are having problems I downloaded the upgrade for Itunes now have a error 7 message and a MSVR80.dll missing- I unistalled and re-installed . Fixed Net 4 - no luck - did all that was said on Apple support - did the "repair " program - no help
Is there a fix - ? Does Apple monitor this site - I last my Itunes lib on my I pad - which is not connected I use Windows Vista
Any help out there

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.

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

Reboot and reinstall iTunes.
I hope this helps.

I can't install iTunes on Windows 7. "An error occurred during installation of assembly"

I recently purchased an iPhone 4s. This product requires me to insall iTunes on my pc, which runs Windows 7 64bit. However, when installing iTunes I keep recieving the same error message-- An error occurred during the installation of assembly 'Microsoft.VC80.CRT,type="win32",version='8.0.50727.4053',publicKey Token="1fc8b3b9a1e18e3b". ProcessorArchitecture="amd64" HRESULT: 0x800736B3
I've already looked over many previous forum posts and haven't been able to find a suitable solution to this yet. I had iTunes on my computer previously but deleted it after I had freezing trouble. I have ensured that all old files have been removed. Bonjour gave me some trouble but I think I have dealt with that now. Also, I have been experiencing some failures with windows update-- service pack 1 for windows seven and some security updates mostly-- which I am yet to solve. I really have no idea what to do as I would like to run my iPhone on the latest iOS. If anybody could help me I would be forever grateful.
Thanks, heattr.

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).

Itunes was working fine. Tries to install latest upgrade and get error message about an invalid character in the path "Program Files (x86)". PC, Win7, nothing else appears to be having same issue.

Thanks b noir,
I tried this solution without success. After FixIt ran and didn't find a problem, either in looking for issues with "software upgrade" or "iTunes" it kindly offered to help me uninstall iTunes. I had thought of this as a possibilty but it seems to me that if you do that you lose a lot of "non-native-to-Apple" information you might have entered. I did this once and recovery was painfull. Is there a way to uninstall iTunes without losing all of that sort of thing? Any help would be appreciated.

Itunes install error message - program not found ...x64/difxinst64.exe

itunes install error message - program not found ...x64/difxinst64.exe
no problems with ITunes on Dell Inspiron Windows 7 until yesterday. ITunes version 11.0.2. iphone won't connect stating required software is not installed. uninstall and install 64 bit version of iTunes. I have 64 bit version already. I have uninstalled and reinstalled 5 times already. When re-installing ITunes get error message c:\programdata\34be82c4-e596-4e99-a191-52c6199ebf6\x64\difxinst64.exe. file does not have a program associated with it for performing this action. please install or create an association in the Default Programs control panel. iTunes install continues after the difxinst64.exe error message but then get the iphone cannot be used error message again. therefore, I can't sync my iphone with iTunes until I figure this out.
can't win for losing. had iTunes on my windows 7 laptop for 4 years. first time I've ever encountered this.

I am a PC Tech and had a customer with this issue. Ran across this post in my search and ended up finding the solution on my own. The problem isn't with the iTunes software but the installer for the GEARAspi drivers. Really the issues is with the file type asssociations in the windows registry. On the system I was working on the HKCR key for .exe should point to the exefile key but pointed to nothing. To fix it create a new txt document and paste the following in (only paste what is in between the [code][/code] tags):
[code]
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.exe]
@="exefile"
"Content Type"="application/x-msdownload"
[HKEY_CLASSES_ROOT\.exe\PersistentHandler]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"
[/code]
Now change the extension from .txt to .reg. Then right click and select merge. iTunes should now install properly.

I'm trying to re-install itunes. I keep getting an error that says "Apple Moble device failed to start" Verify you have sufficiant privlidges to start system services. Anyone have an idea how to fix this?

I'm trying to re-install Itunes. I keep getting an error message that says....
"Apple Moblie Device failed to start, Verify you have sufficiant privileges to start system services"
Does anyone know what this means, or how to fix?
Thanks

Itunes dll errors, APPLE SYNC error on bootup, sync error.....solution!

One brilliant guy came up with this solution in this forum and has worked on 5 straight PC's. The thing is, I found another thread that helped also. In addition to this, if you are getting the Apple Sync Error, or still have problems after doing this procedure, go into uninstall programs and remove the MobileMe application. It is appearing to be a major contributor to the errors with Apple Sync! Thank you for your help guys!!!!!!
Okay, we're going to uninstall both iTunes and Apple Application Suppport this time. When we reinstall iTunes, that should reinstall Apple Application Support as well. We'll take a few additional explicit precautions along the way too. Best to print these instructions out, because at one stage of proceedings you won't be able to use a web browser.
Preliminaries
Download and save a fresh 64-bit iTunes installer to your hard drive. (Don't run the install on line and don't start the iTunes install just yet.)
http://support.apple.com/kb/DL925
Now, quit QuickTime (if you have that open) and Safari 4.0.4 (if you have that installed and open). Both applications use Apple Application Support, and they will interfere with the uninstall if you have them open.
Uninstall phase
Head into your "Uninstall a Program" control panel. Uninstall iTunes. Uninstall Apple Application Support.
(From this point on until we reinstall Apple Application Support, neither QuickTime nor Safari 4.0.4 will be able to run.)
Next we'll remove any leftover program files and folders.
(1) Open "Local Disk (C:)" or whichever drive your program files are stored on.
(2) Open the "Program Files (x86)" folder.
(3) Right-click on the iTunes folder (if it still exists) and select "Delete".
(4) Staying in Program files (x86), find and open the "Common files" folder.
(5) Open the "Apple" folder.
(6) Right-click on the Apple Application Support folder (if it still exists) and select "Delete".
Now empty your Recycle Bin and restart the PC.
Reinstall Phase
After the PC restarts, do not open any other applications. Disconnect from your network and/or the internet. Switch off all your security software (firewall, antivirus and antispyware).
Now start the install by doubleclicking the iTunes64Setup.exe file you downloaded earlier.
Reenable all security software prior to reconnecting to your network and/or the internet.

Thanks to all on this thread.. same problem, same solution.
This time it was on Win 7, the setup worked fine for awhile, and then SWMBO "did something" and it stopped working. Much debug later, found the log message and realized that there was a streaming problem, but could not figure out if it was the router, my wireless network (I'm using it tied to my existing wireless network) or what. New hardware, fully up to date firmware.. Argh!
I finally found this post, found the offending file ( ..\Users\xxxxxxx\AppData\Roaming\Apple Computer\Preferences\com.apple.iTunes.plist ) and simply moved it to another folder. Restart iTunes, and all is copacetic.
Clearly this is a software issue in iTunes, and is happening accross HW and SW platforms for better than 2 years now..
I love the device, but the only reason I have it is to drive the stereo. They should fix this one...

Errors occuring during Itunes instalation

When I try to install itunes, it says: The installer encountered errors before itunes could be configured. Errors occured during instalation. Your system ha snot been modified... What should I do to install Itunes?

Same problem here :-( I am trying to install itunes for 64 bit Windows 7 64 bits from the official website to 5 months old HP Pavilon dv6 laptop. Have deinstalled the programme, cleared the caché, restarted my laptop but problem persists :-( What is the solution to this please?

HELP!!!
I am trying to install iTunes on my Windows 7 laptop and get this error:
"The installer encountered errors before iTunes could be configured   Errors occurred during installation. Your system has not been modified"
Arghhhhh!! I've tried different browsers and various other things suggested on other posts to no avail

Ok people, I think I have found the solution !
If you click on the start button from your desktop screen.
Then in the "search programs and files" field type : apple software update - you can find the apple installer.
Click on the apple software update line and let the machine run it's course. I recommend updating whatever it wants to , ie: safari 5, quicktime, itunes....
I then restarted my computer and it seems to be working now !
Good luck everyone !

HT1420 itunes install error in Vista

I (sadly) have Windows Vista Home Premium 64 and no matter what I try, I cannot install iTunes (9, 10, OR 11) successfully. I get an error that is very non-descript, stating my installation could not be completed. Period. No error number, nothing. Screenshot for your pleasure:
I have disabled my Norton Anti-Virus and "Smart Firewall" for the install, but that doesn't matter. And I tried re-installing. Same results.
Is there a way to view and shop at iTunes via my browser (IE8) without installing itunes program?
I thoroughly hate my operating system, and I only need to get onto iTunes to download the songs I want from the American show "The Voice".
It's very sad that there are people who cannot use their social media to vote for the contestants because iTunes and Vista64 aren't friendly.
Ok, aside from my rant, does anyone have direct links or help I can try?
Thanks!

However, when I attempt to open said file, I get this message: Files\Common Files\Apple\Mobile Device Support\bin is not accessible. The file or directory is corrupted and unreadable.
Try doing a disk check on the drive that that file is located on.
Go "Start > Computer", select Properties, and in the Tools tab click "Error checking".
Does the disk check find/repair any damage? If so, does an iTunes install go through properly afterwards?

Vista itunes not installed correctly. Error 7. Windows error 998. Itunes helper not installed correctly. Service Apple Mobile Device failed to start. Insufficient privileges.

OK, spent about 25 frustrating hours so far this weekend doing everything recommended on numerous threads here -- uninstalling and reinstalling itunes and all Apple items. Help?
I am using Windows Vista home premium. After the last iTunes update to 12, it suddenly would not work. I followed, to a T, all instructions to uninstall all Apples software, in the correct order, reboot, download the latest iTunes, run as administrator, plug in the iPhone 5S, let the driver install, and then finish.
Along the way, I received the error that "Service 'Apple Mobile Device' (Apple Mobile Device) failed to start. Verify that you have sufficient privileges to start system services." I am the administrator and have privileges. (I previously followed instructions from anther thread to change the read-only privileges for Apple folders, but to no avail. I also deleted every file with the word Apple in it after I uninstalled everything.) I did a retry and then an ignore during installation of the AMD error, which I have received 10 times.
The other error I keep getting is: "iTunesHelper was not installed correctly. Please reinstall iTunes. Error 7." I have done that 20 times.
Other frequent error: "iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 998)."
I followed other threads suggestions to install Windows .NET versions 3.5 and 4.0. No help. I also looked for various specific Apple files in various folders for DLLs, etc. Not present. I have rebooted 50 times and tried different users on my home account as well. Nothing.
I also followed instructions to Manage my computer under "services." Under Apple Mobile Device, the setting is for "automatic." When I try to get it to "start," the error I receive is "Windows could not start the Apple Mobile Device on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion." (I followed previous thread instructions to use the CMD prompt to stop it. That caused problems because the status was then "stopped," but I was able to restart it later once I figured that out -- but with the 1053 error again.)
I think I've tried every suggestion in every thread for the four errors I keep getting (AMD failed to start; iTunesHelper Error 7; Windows error 998; and AMD Error 1053.) I am fresh out of ideas and very frustrated. I mostly want to make sure I don't lose my music and photos, which I was about to sync.
The only other thing I see that is strange on my computer (which I discovered along the way) is that I cannot receive automatic windows updates and have not had an update since 2012. My iTunes worked a month ago, so that was obviously not a show-stopper in the past, but perhaps there is a Vista update I need for iTunes 12? I have service pack 2 for Vista. I have followed all threads to try to set my windows to automatic update, but no joy there either. It checks for updates and then fails. I followed instructions and did run an installation to install windows automatic updates, but that doesn't work either. I tried 10 times. It runs and takes a while, but is never able to successfully update windows. It says "checking for updates" for a while. Then it dies. My last update was 6/19/12 (failed) and it says the most recent check was 6/22/12, but I have tried 20 times on 10/31/14 and 11/1/14.
When asked to "Install new Windows Update software" to check for updates, I have done so 10 times. It downloads and installs, but never works.
It's an old Dell desktop computer from 2006, and I'm using an iPhone 5S. I am fresh out of ideas. Anyone really smart here?
Thanks.
Tristan

Upon latest reboot, I also received this error message: "The application failed to initialize properly (0xc0000005). Click OK to terminate the application."
Then I got the iTunesHelper not installed correctly error again.
Then the "Windows can't check for updates" error message.
Then "Apple Push has stopped working." Then a quick DEP error message that disappeared but said something about Apple Push being closed.
I'm also getting denials of service logged by McAffee. Not sure if I'm getting a virus/attack or not.
Not sure if it's a problem with my old desktop machine, my Windows Vista updates, or iTunes, but I'm very frustrated and out of ideas to try.
Thank you for your help!
Tristan

ITunes install fails due to Error Code

I'm trying to install iTunes and I get the message Service 'Apple Mobile Device' failed to start. Verify you have sufficient privileges to start system services. I then have 3 options - Abort - Retry - Ignore which provide no success. If I ignore it the installation process completes however it states that the installation failed 'Error Code 7 (Windows error 126)' re-install iTunes. I've tried running the download as administrator with no success.

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 suitable for your PC (there's a 32-bit Windows version and a 64-bit Windows version):

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.
