"apple application support was not found" now what?

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.)

Hi b noir,

I've been following your posts for my iTunes compatibility problems with Vistas. So far, progress has been steady - but now I'm stumped.

Apple customer service wanted me to Uninstall/Reinstall iTunes - intending to walk me through the problematic new-device setup. Prior to now, iTunes has had quirks with Vistas, but we were running just fine. However, per Apple, I Uninstalled and now - I just cannot get it Reinstalled.

I cleared a few hurdles until I got this "Apple Application Support not found error 2" message.

Again, I followed your steps and after trying the standalone AAS install, I get the following message:

"A later version of Apple Application Support is already installed on this computer."

So, between these two messages:

AAS not found error 2

"A later version of Apple Application Support is already installed on this computer."

I don't know what to do next.

Can you please advise?

Still does not work

Not able to get winrar

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 the page in case one of them applies.

The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try theiTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.

The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if a particular component won't install normally.

Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.
