Problem upgrading to itunes 9.2 on windows vista

With that particular combination of error messages, It's most likely that your variety of error 7 is being caused by a damaged Apple Application Support. (iTunes needs a properly functioning AAS in order to work correctly.)

Do you have a a 32-bit or 64-bit version of Vista? (That makes a difference to how we go about attempting to fix this.)

Many thanks.

We'll try uninstalling/reinstalling both Apple Application Support and iTunes this time around, taking a few other explicit precautions just in case. Best to print off a copy of these instructions, because at one stage of proceedings you won't be able to use a web browser.

Preliminaries

Download and save a fresh copy of the iTunesSetup.exe (installer file) to your Hard drive. (Don't run the install on line, and don't start the uninstall just yet.)

http://www.apple.com/itunes/download/

Quit any recent version of the QuickTime Player, Safari for Windows and/or the MobileMe Control Panel for Windows if you have them installed and open. (They all use Apple Application Support, and may interfere with the AAS uninstall if they are open.)

*Uninstall Phase*

Head into your "Uninstall a program" control panel. Uninstall iTunes. Uninstall Apple Application Support.

(From this point onwards, recent versions of QuickTime, safari and the MobileMe Control panel will not launch, until we get AAS reinstalled by reinstalling iTunes.)

Next we'll remove any left-over program files and folders.

In "Computer" open "Local Disk C:" (or whichever drive you have your program files installed on).
Open the "Program Files" folder.
Right-click on the "iTunes" folder (if it still exists) and select "Delete".
Open the "Common Files" folder.
Open the "Apple" folder.
Right-click on the "Apple Application Support" folder (if it still exists) and select "Delete".
Empty your Recycle Bin.

*Reinstall Phase*

Restart the PC. After the PC restarts do not open any applications. Disconnect from your network and/or the internet. Now switch off all your security software (firewall, antivirus, antispyware).

Now start the reinstall by doubleclicking the iTunesSetup.exe file you downloaded earlier. (This should also reinstall Apple Application Support.)

Reenable all security software prior to reconnecting to your network and/or the internet.

Did the reinstall seem to go through properly? If so, does iTunes launch properly for you now?

I was just wondering if this procedure will erase all my itunes content for example my music.

No, you should be okay, the default location for iTunes library files and content files is different. That's off in C:\Users\<YourUserAccountName>\Music\iTunes\ on a Vista system. So, assuming your content and the library are in the default locations, the uninstall/reinstall instructions won't touch any of your content.

(That being said, it's still a good idea to have a backup of your content in case of disasters.)

It never rains, but it pours.

Those ones are generally caused by underlying problems on the PC that can prevent Windows Updates from installing. So my main strategy with them is to try to fix the Windows Update issue. If we can get Windows Updates flowing again, we can generally fix the Apple Application Support installation problem +en passant.+

Head into your Windows Update and try to download new updates. Do some of them fail to install? If so, head into your Update History and doubleclick on the failures. What error message code appears in the little box that comes up? Are they also 80070246s, or some other error message codes?

Tricky to tell which one of those is at the heart of matters.

So perhaps the first thing to try might be an sfc /scannow:

[How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7|http://support.microsoft.com/kb/929833]

Does the scannow work correctly? If not, what error message do you get when trying to run it?

i am the admin on my pc but it says i have to delete it as administrator and i cannot delete the programme right at the end ?

Yes your the admin, but you cant delet the other admin? You can right click on your programm and choose "run as admin", it works fine. If you are a command line junkie like me, and auto have been testing out Windows 7 or Vista… one of the first things you’ll notice is that there is no way to run a command from the run box in “Administrator” mode. Until now.

To try this out, go to the run box and type in something (cmd, for example)

Now instead of hitting the Enter key, use Ctrl+Shift + Enter. You will be prompted with the obnoxious User Account Control dialog… but it will then open up a command prompt in Administrator mode.

Hint: You can use Alt + C to quickly close the User Account Control dialog in Vista, or Alt+Y in Windows 7.

This actually worked for Windows 7.

Thank you!

I had the same problem with iTunes 10.1. It works perfectly now without losing any data. MANY THANKS.
