If you did not use the linked article to reinstall iTunes, you need to try it again following those instructions.

Also check that your virus software is not interfering with what you are trying to do.

Error 2 (Windows 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:

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.)

Is that a nano, albert?

I'm no expert with that particular error, but if so the following document is probably a good place to start:

iPod nano: Error message saying that iPod 'could not be identified properly'

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? (For example, 8007000B.)

Hello noir,

I did the Windows Update... And I am stuck with two Windows Update.

1) Error code 643 - Security Update for MIcrosoft Visual C++ 2008 Service Pack

2) Error code 9C47 - Windows Internet Explorer 9 for Windows 7 for x64 - based Systems

I don't know what to do now, I have tried plenty of time to update but it always fail.

I even tried the Windows Update troubleshooter. Please help me sir... Please.

Doublechecking, red. Is that first one the "Security Update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243)"?

b_noir, yes, that is the correct update (KB2538243)...I am having the exact same terrible issues that has destroyed my iTunes on my laptop. Any solutions yet? Please help.

After days of unsuccessful attempts of various suggestions found on the web, I finally fixed it the hard way by basically reinstalling Windows (In-place upgrade):
