I have actually answered this question 🙂
SO HERE YA GO 🙂
I have problems Installing updates all the time. Its a pain in the butt, but the way I have to install it takes a bit more than anyone elses. First you have to make sure that Any old Itunes files are deleted. The ones that were causing problems for me were
C:\Program Files\Common Files\Apple
C:\ProgramData\Apple
C:\ProgramData\Apple Computer
BUT BEFORE YOU ERASE THOSE FILES FOLLOW THE STEPS BELOW
* You're going to need Winzip or Jzip (Free- http://www.jzip.com)*
STAGE 1:
After you have winzip or jzip go ahead an choose between option 1 or 2:
OPTION 1 (IF YOU'RE UPDATNIG):
1. go to Itunes Menu bar >HELP > CHECK FOR UPDATES
2.error will occur, instructing you to go to TOOLS> DOWNLOAD ONLY
3.Go ahead and Download and save them to your Desktop.
THEN:
Go ahead and uninstall everything in this order.
Using Control Panel\Programs\Programs and Features
- iTunes
- QuickTime
- Apple Software Update
- Apple Mobile Device Support
- Bonjour
- Apple Application Support (iTunes 9 or later)
Go one by one until everything is uninstalled.RESTART YOUR COMPUTER
OPTION 2 (IF YOU'RE DOWNLOADING):1.Go To : http://www.apple.com/itunes/download/
to download iTunesSetup.exe
2. go ahead and open the folder where the file was downloaded to
3. Right Click iTunesSetup.exe
4. Extract the files to your desktop or folder
5. IF you previously had itunes installed you will need to make sure all of these programs are uninstalled in this order
- iTunes
- QuickTime
- Apple Software Update
- Apple Mobile Device Support
- Bonjour
- Apple Application Support (iTunes 9 or later)
Go one by one until everything is uninstalled.
RESTART YOUR COMPUTER if you previously had itunes installed.
STAGE 2:
Then Go ahead and look for these folders & Delete each one.
C:\Program Files\Common Files\Apple
C:\ProgramData\Apple
C:\ProgramData\Apple Computer
Once that is complete
Go ahead and click on the Itunes installer & install ITUNES
The install will roll back during Apple Mobile Device installation, but should still install.
IN ORDER TO SYNC properly do not stop there.
YOU are going to need Winzip or Jzip (what i recommend) to extract a couple of files.
First file:
Right Click on the APPLE MOBILE DEVICE installer and extract it to a New folder on your DESKTOP.
After you have done so, go ahead and open this folder
Second FIle:
In the Folder you have extracted, you will find a second file named THIS CONTENTS OF THIS FILE MUST BE EXTRACTED AS WELL!
Extract this file to a NEW folder>>>> NAME THIS FOLDER Mobile Device Support
AND EXTRACT (OR CUT & PASTE) IT TO THIS LOCATION C:\Program Files\Common Files\Apple
Once you have done all of this go ahead and open Itunes
To ensure sync and everything else is working properly.
Hope this helps! in some way.
