Apple Application Support Installation Error "8.0.microsoft.vc80.CRT"

When I tried to upgrade to the latest iTunes on my Vista system, I get the following: "error occurred during installation of assembly policy 8.0.microsoft.vc80.CRT." I have tried several suggestions on various threads here, including this one: http://discussions.apple.com/thread.jspa?threadID=2251840&tstart=0&messageID=107 35122#10735122 all with no success.
I have used WinRar to open the iTunes installer to check each .msi, and it appears the culprit is Apple Application Support.
Looking at some of the other threads on this problem, it seems like the folooiwng information is needed: I am running Vista Ultimate (64-bit). The only update I've had fail recently and consistently is Update for Microsoft XML Core Services 4.0 Service Pack 2 KB973688 with error code 643, but error code 80070003 when I downloaded it separately and tried to install. I currently have a copy of Microsoft Visual C++ 2005 Redistributable and Microsoft Visual C++ 2005 Redistributable (x64) on my installed programs list. Can provide more details, if needed.
I would appreciate any help. I am getting pretty close to thinking I need to go nuclear and re-install my OS.

Hi
You are looking in the right place for solutions to this, b noir has been most involved.
There seem to be two main issues - failure of Windows Updates and the Visual C++ 2005 redistributable issue.
If you search the forum for redistributable limited to the user name b noir, you should find helpful material.
If your Windows updates are failing, you can search the Microsoft site for the error number, here is an example:

Hi Gurmo,
HRESULT: 0x80073712 means ERROR_SXS_COMPONENT_STORE_CORRUPT, and it is one of the error codes listed at this
KB article.
I suggest you run the System Update Readiness tool and check if the error still persists.
There is a similar thread for your reference.

I keep getting an apple application support missing error. Therefore I cannot get Itunes to work on my PC.

I have downloaded ITunes numerous times on my PC so I can sync with my Ipad and Iphone. I get "congratulations" you have downloaded ITunes followed by a message stating that apple application support is missing. Is there a way to download this as a stand alone?

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/
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, does iTunes launch properly now?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

Any ideas?

PLEASE!!!! Someone help...I have spoke with Apple at least 4 times and they act like they have never heard of this problem. I have spoke with Gateway who will not help me because it is "3rd party software" and just the other day I took it to Geek Squad who told me to downgrade to xp for 200 bucks. I have been working on this since Christmas (when I got my Iphone). I took my phone to another computer that has xp and it worked fine. Anyway I am getting the same error message as all of you.

Hi,
I cannot install iTunes after an update went wrong. Seen another with exact same problem but without an answer. Error message is:

OK. If both of you are Windows 7. Make sure you go to Windows update (START button, type in Windows Update). Check for updates and update whatever that are available. (especially Microsoft .NET Framework 4 )
After that see if you still get this error message.
The last resort would be to unistall and reinstall the whole thing.
Follow the steps below:
1. Go to Microsoft website to fix install and Unistall problems. Click "Run now" from Fix it to remove all iTunes & related installer files:
http://support.microsoft.com/mats/Program_Install_and_Uninstall

2. You should remove all instances of iTunes and the rest of the components listed below:
it may be necessary to remove all traces of iTunes, QuickTime, and related software components from your computer before reinstalling iTunes.
Use the Control Panel to uninstall iTunes and related software components in the following order:
iTunes

Error in installing Apple Application Support preventing installation of iTunes, please help

I am trying to install iTunes for Windows (64 bit) but have been unsuccessful because I receive the following error message: "Microsoft.VC80.CRT,type+"win32",version="8.0.50727.6195"publicKeyToken="1fc8b3 b9a1e18e3b",processorArchitecture="x86". Please refer to Help and Support for more information. HRESULT:0x80070BC9.
After receiving this error message the installation continues, but iTunes is never able to launch because it says that Apple Application Support is not installed. I have tried separately installing Apple Application Support only to receive the same error message as above. Please advise on how I can install iTunes properly or what this error message means.

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.

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
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?

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”’.

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\

Reboot and reinstall iTunes.
I hope this helps.
