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.)

Hi b noir,


I tried the stand alone installation of apple application support as you suggested and received this error message:


An error occurred during the installation of assembly 'Microsoft.VC80.CRT,type="win32",version="8.0.50727.6195",publicKeyToken="1fc8b 3b9a1e18e3b",processorArchitecture="x86'". Please refer to Help and Support for more information. HRESULT:0x8007054F.


Please help me restore my music world if you can 🙂


Thank you very much,

Ken

These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.


Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?


If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? Are they also 8007054F, or some other number? (If they're another number, what number are you getting?)

It is always these four updates that fail. I've tried downloading and installing them seperately from apple downloads. I've tried various recommended fixes, and nothing I can figure out works. Before these problems, itunes worked on the computer for a year.


Thank you again for wanting to help me.

Unfortunately, these aren't particular Update errors I've done a lot of work on.


Scratch that, ken ... overnight, I unexpectedly find myself working on two of these at once.


A commonality between the two is the 643 on this one:


1) Security Update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243)

Installation date: 12/17/2011 7:58 PM

Installation status: Failed

Error details: Code 643


Are you able to download and install that one directly from the Microsoft Downloads Center (rather than using Windows Update)? Or do you just get a 1935 install error?
