ITunes doesn't launch error 1 "apple aplication support is not found"

Every single time I attempt to open iTunes, it doesn't and it shows me a pop up telling me that the ERROR 1 occured, that the apple aplication support was not found, it tells me to uninstall and install itunes and so i've done several times, but nothing. PLEASE help me if you can i'm going nuts here!!!!!

Try removing all iTunes related software and then reinstalling.
Use the method in this article:

Vista
http://support.apple.com/kb/HT1923
If an uninstall doesn't work, you need to use the Microsft Installer cleanup utility to remove it.
Download and install Microsoft Installer cleanup utility, there are instructions on the page as well as the download. Note that what you download is the installer not the program – you have to run it to install the program. The installer doesn't give any message to confirm the installation.

When trying to download the latest version of iTunes, I receive the following error "Apple Application Support was not found", any suggestions?

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 one component, such as Apple Application Support, won't install normally.

Please help me with this error: "Apple application support was not found... Error 2"

Can anyone please help me with this error: "Apple application support was not found... Error 2"
I've followed the instructions by removing all Apple files from my laptop, but when I reinstall the iTunes software it still comes up with this message:
"Apple application support is required to run iTunesHelper. Please uninstall iTunes, then install iTunes again. Error 2"
Thank you

iTunes "Apple Application Support is required... Error 2" and possible fix.
I know this is a bit late but I came accross this thread trying to resolve this same problem and came up with a solution that worked for me, so thought I would share it here too. I hope it helps someone else.
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:

Reboot and reinstall iTunes.

HT1923 I can´t reinstall itunes. I updated and after downloading the latest version and installing it the error message: "apple aplication support was not found. it is required to run itunes. uninstall and install again. Error 2

I bought an iphone 4s. After plugging it via usb to my computer itunes demanded to update version to 10.3 or higher. I uninstalled itunes, downloaded latest version (11.0.2) and during installation process on "activating services" it shows error message: "installation failed, verify administrator priviliges" which i have because i sign in as my pc administrator. I click on ignore and it tells me itunes has been succesfully instaled but when i try to run it it shows the error message: "apple application support was not found. It is required to run itunes. Uninstall and install itunes again. (which i have done several times) error 2 (windows error 2)." Someone please help me with this problem. Thanks.

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 instead you get an error message during the install, let us know what it says. (Precise text, please.)

Cant install itunes 10.5 keep getting Apple Aplication Support - could not open key error

I ve been getting this message over and over:
Apple Application Support
Could not open key:
UNKNOWN\Components\DA42B......................
Verify that you have sufficient access to that key, or contact your support personnel
I have uninstalled all Apple soft and tryed to reinstall itunes 10.5, but there is no help. I run win 7 64 on toshiba notebook

Open regedit using "run as administrator".
Go to the registry key:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionInstallerUserDataS-1-5-1 8Components
...and selected the folder DA42BC89BF25F5BD0AF18C3B9B1A1EE8
(there are three folders with very similar names A,B & C you want the first one)
Right click & choose Permissions
Click Advanced, and then the Owner tab
Type (not administrators) in current owners field and check the box to replace the owner on subcontainer and volumes
Apply settings and then click Permissions tab. Once again, add (not administrators) to the list of permission entries, then click edit and check all permission boxes. Also click the 2 bottom boxes concerning the inheritable permissions.
[Note: In my case I was a member of administrators and administrators was already set in all of the above settings - I've no idea why it needed to be set to my user rather than the administrator group, anyway it solved the problem for me]
Click OK
Now back on the main permissions tab, add in the user name window and then check full control and read checkboxes. Click OK.
On the menu bar click file > exit
But if u have the message pop up more then once then just make the permissions for the entier S-1-5-18Components folder

Under normal circumstances, an uninstall/reinstall doesn't touch your content. (That being said, it's still always a good idea to maintain a current backup at all times in case of disasters.)

When I try to open iTunes, Error 2 appears saying that iTunes won't open b/c "Apple Application Support was not found". What do I do???

If your problem is only w/iTunes, you really should re-post over in the iTunes for Windows forums instead of the iPod forums.

What does it mean when it says "Apple Application Support was not found"

Ok. I uninstalled everything that was related to itunes because it wouldn't let me connect my ipod to itunes. a few days ago I think I uninstalled something that I needed because now I can't even open itunes. It keeps saying "apple application support was not found" when I try to open the program. And it says :"Error 2 (Windows error 2)" I've tried to download everything. itunes 64-bit, 32-bit, update, latest version, and something else I believe. Why can't I get itunes back on my computer? Please help!
