Unable to Reinstall iTunes - error message: "Apple Application Support was not found"

When attempting to update my iPhone today, my iTunes would not open. I followed the instructions to completely uninstall iTunes, Apple Software Update, Apple Mobile Device Support, Bonjour, and Apple Applications Support. I then attempted to reinstall iTunes, and everything went perfectly until I attempted to open iTunes. When attempting this, I am receiving the message "Apple Application Support was not found. Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again. Error 2 (Windows error 2). Any advice on how to "get this back"?

Read through the user ip http://discussions.apple.com/docs/DOC-6562 for the best solution.

Hi texasslagle,
It sounds like you are having issues installing iTunes on your Windows 7 PC, a frustrating situation I am sure.
There is an article that you may want to use to try to complete your install here -

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.)

Have a new itouch. I'm having trouble downloading iTunes. I keep getting the error message: Apple Application software was not found. Apple application support is required to run iTunesHelper. Please uninstall iTunes, then install iTues again. Error 2.

I have a new iTouch. I'm having trouble downloading iTunes. I keep getting the error message: "Apple Application Software was not found. Apple application support is required to run iTunesHelper. Please uninstall iTunes, then install iTunes again. Error 2." I have uninstalled and tried installing again and get the same error message. What do i need to do?
Lg

Install 7-Zip (free), or a free trial of WinRAR, and use one of them to extract the contents of the iTunesSetup.exe or iTunesSetup64.exe installer file, then try installing AppleApplicationSupport.msi as a standalone component. Even if it won't install you may get a more useful error message as to why not.

If you run into the "another installation" message even after the reboot of the PC (which is an excellent idea by HTP ProXy), reregistering your Windows Installer Service is worth a try.
First, launch a command prompt as an administrator. In your Start search, type cmd then right-click on the cmd that comes up and select "Run as administrator".
At the command prompt:
Type %windir%\system32\msiexec.exe /unregister and hit enter.
Type %windir%\syswow64\msiexec.exe /unregister and hit enter.
Type %windir%\system32\msiexec.exe /regserver and hit enter.
Type %windir%\syswow64\msiexec.exe /regserver and hit enter.
Restart the PC and try another reinstalll.

HT1926 I cannot get iTunes to load -- "Apple Application Support was not found". I have tried multiple things to fix it and nothing works including re-installing.

Try b noir's post Standalone Apple Application Support install to see if that can repair the problem or provide futher information, otherwise try reinstalling again as shown in Troubleshooting issues with iTunes for Windows updates.

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.

ITunes wont load Apple Application Support was not found

I have been having a lot of trouble downloading itunes. I had it on my laptop and then the laptop crashed. I tried to re-install,and it goes smooth then at the end. I get a window message that has a red and white X that says:
Apple Application Support was not found
Apple Application Support is required to run iTunesHelper. please unistall iTunes, then install iTunes again.
Error 2
ok
Can anyone help me PLEASE?
Thanks

With that one, let's try uninstalling both iTunes and Apple Application Suppport. 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 iTunes installer to your hard drive. (Don't run the install on line and don't start the iTunes install just yet.)
http://www.apple.com/itunes/download/
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 "Add or Remove Programs" control panel. Uninstall iTunes. Uninstall Apple Application Support (if it is listed in there).
(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" folder.
(3) Right-click on the iTunes folder (if it still exists) and select "Delete".
(4) 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 iTunesSetup.exe file you downloaded earlier.
Reenable all security software prior to reconnecting to your network and/or the internet.
Did the install seem to go through okay? If so, does iTunes start launching properly again?

Does it install properly for you? If so, does iTunes launch properly now?
