Cannot upgrade ITunes on my PC at ALL

Hello. I am running Windows Vista Home Premium on a Dell Inspiron 1525 laptop that I purchased in August 2008 and I own an iPod touch 2nd generation that I bought in January 2008. I was able to use iTunes on this laptop and with this device fine until (some time ago) I tried to upgrade to iTunes 9 via Apple Software Update. However, something always went wrong with the update and iTunes could never open if upgraded even if it supposedly installed correctly. I eventually had to downgrade to 8.2.1, downloading this downgrade from a third-party site, to get iTunes to be functional at all.
I have since repeatedly tried to upgrade to the latest version of iTunes, first 9, then the various upgrades of 9, and finally now to version 10. However, I still cannot get it to install properly! Here is what happened when I tried to install it today, with screencaps I made via Print Screen.
At first, the install seemed to be running normal. Then, this error popped up:
http://img.photobucket.com/albums/v328/Dani17/ituneserror1.png
I clicked OK and it rolled back whatever action was then happening and went on its merry way.
As it got towards the end, the install stalled for some time, looking like so:

A little later, a "Windows Installer has closed" error popped up, prompted by Data Execution Protection:
http://img.photobucket.com/albums/v328/Dani17/ituneserror2.png
I clicked it away and the install continued. Long story short, the install finished and I was greeted by this happy window:

However, when I clicked "Finish," this error came up:
http://img.photobucket.com/albums/v328/Dani17/ituneserror3.png
Now, Apple Application Support is supposed to install as part of the iTunes installation, yes? So how could it be missing?!
Anyway, this explanation more or less displays what happens to me every time I try to install and/or upgrade iTunes. I have tried basically any method I can find for fixing this, and nothing has worked! Help!!!!

Go to start -> control panel -> programs and features -> scroll down to iTunes -> highlight iTunes -> click uninstall -> reboot PC -> go to http://www.apple.com/iTunes -> download and install iTunes 10...
I had this exact same issue today on one of the computers I was working on at work...

Still cannot upgrade iTunes

This is an update to an earlier question I had posted.
I desperately need help!
I have a Dell Inspiron 1525 laptop with Windows Vista 32-bit and a 2nd generation iPod touch running iOS 3.1.3 (7E18). However, I would, obviously, like to upgrade to the latest iPhone OS.
The problem? I can't.
Ever since iTunes 9 came out, I have been unable to successfully upgrade iTunes. I can only get up to version 8.2.1 to work on my computer. The install will appear to go fine, but I'll get various errors and even after getting a "iTunes was successfully installed" finish window, get an error saying that iTunes cannot open because Apple Application Support was not found, even though Apple Application Support installs as part of the iTunes install for iTunes 9 and higher. I also get an error trying to update via Apple Software Update.
I have literally tried every single thing I can think of or find online, including the "trouble installing iTunes" troubleshooting instructions on Apple's website. I am not sure I can take this to Apple for repairs because my iPod is out of warranty. Plus I have a PC, not a Mac. I did call a nearby Apple Store to see if I could bring it in, only to be told they don't work on PCs. The guy then asked what my issue was, and I told him. He told me to try Googling it, which of course I have already done -- many, many times.
To prove my claim is real, I have been making screenshots of all my errors. Here they are:
When installing iTunes from the website or from a prompt within my current iTunes version, after a bit I tend to get this error:
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/ituneserror1.png
I click ok, the install continues, and then on occasion I have gotten this error:
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/ituneserror2.png
I click out of it, the install continues, and then when it's almost to the end, it tends to stall:
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/itunesstall.png
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/itunesstall2.png
Once recently while it was stalled, I got this error:
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/applemobiledeviceerror.png
(I should mention, in relation to this error, that I am the only user of the computer on which this is occurring, and I do have admin privileges on it).
Yet after all that, I still get this happy screen:
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/itunescongratsinstalled.png
I click "Finish," only to get these errors:
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/ituneserror3.png
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/ituneserror4.png
As I've said, I've tried everything. Someone suggested I install QuickTime separately, which I did recently, only to get this error:
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/quicktimeerror.png
And as I said before, trying to do the update via Apple Software Update doesn't help either:
http://img.photobucket.com/albums/v328/Dani17/iTunes%20Upgrade%20Error%20Screens hots/ituneserror_applesoftwareupdate-1.png
What should I do???

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. Do they fail to install? If so, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you?

Cannot upgrade itunes v 10.5 to 10.7 on a PC due to Bonjour error, what can I do?

I have tried to upgrade itunes 10.5 to 10.7 on my PC but keep on getting "older version of Bonjour cannot be removed". I have tried to locate msicuu2.exe which was suggested might help but I understand that microsoft has withdrawn it as it conflicts with office 2007, which I have. Anyway I was unable to find it anywhere.
The current version of iTunes 10.5 operates with my iPod Classic but not with my iPhone 4s whose software v6 requires a later version of iTunes.
Can anyone help?

Hi b noir
I have followed your suggestion and this time the itunes installed to give me 10.7. However on restarting the computer the error message from AppleSyncNotifier.exe - Entry Point Not Found "The Procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQLite3.dll."
Is this likely to cause any problems or can it be ignored? What do you think?
Anyway Itunes appears to load OK. I have still to try syncing the iPod and the iPhone. It was the latter that required the upgrade.
Thanks for your help.

Once again - upgrading iTunes - reports library file damaged, all missing

So, I've finally figured it out. When ever I upgrade iTunes, the new version doesn't like the old library file and marks it as damaged.
All content is lost - as far as itunes is concerned. But it's right there on the hard drive. In the itunes folder.
Making a new library file and point the preferences to the content still results in nothing showing up.
No, I have not sync'd since this happened. I have many files in the itunes folders on my HD where the content is not loaded on my itv4.
Is there a magic key combo to have it 'look' at the actual HD contents in the itunes folded and 'find' it ?
No, holding down SHIFT when launching itunes and then creating a new file is not the solution, nor selecting the old library file (says it's damaged).

For general library squiffiness following an upgrade the easiest thing is to restore your last backup, but I guess if it were that simple you wouldn't be here.
*Empty/corrupt library after upgrade/crash*
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the *Previous iTunes Libraries* folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename *iTunes Library.itl* as *iTunes Library (Corrupt).itl* and then rename the restored file as *iTunes Library*. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch (Windows) or Music Folder Files Not Added (Mac) and Super Remove Dead Tracks (Mac) for tools to catch up with any changes since the backup file was created.
When you get it all working *make a backup!*

Cannot upgrade Itunes and Quicktime on my PC

I cannot upgrade on my PC. Everytime I try there is an error on Quicktime. I have tried to uninstall but the programs are protected and will not let me. I get and error message saying it cannot find a certain file. any suggestions? I need help. I am close to wiping out my hard drive and starting over.

+I get and error message saying it cannot find a certain file.+
What's the *full and precise* text of that message? (That might be of some assistance with determining what's going on.) Include error message numbers if you're getting any.

Cannot upgrade iTunes because cannot uninstall itunes 9.0.2.25. Error: The installation source for this product is unavailable. The file c:/... itunes.msi is not a valid installation package for itunes.

I also get the error. "Cannot uninstall the older version of iTunes. Contact your technical support group."
How do I download the itunes.msi for iTunes 9.0.2.25 so that I can remove this phantom and unfunctioning program and then hopefully upgrade to the latest version of iTunes 10.5?
Thanks for your ideas.

Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
To install the utility, doubleclick the msicuu2.exe file you downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Cannot upgrade iTunes

After receiving a new iTunes dl file I tried upgrading and got the following error: The older version of iTunes cannot be removed..." I went online and found a "solution" to the problem but it did not help.
Here is what I did:
Try this and see if this might work for you. Also if you are using this itunes through a School or Corp/company connection that could be causing the error involving Network Connection.
1. open Local Disk C: in My Computer or whichever disk programs are installed on.
2. Open the Program Files folder.
3. Right-click the iTunes folder and select Delete and choose Yes when asked to confirm the deletion.
4. Right click the iPod folder and select Delete and choose Yes when asked to confirm the deletion.
5. Right-click the QuickTime folder and select Delete and choose Yes when asked to confirm the deletion.
6. Delete the QuickTime and QuicktimeVR files located in the C:\Windows\system32\ folder.
7. Right-click on the Recycle Bin and on the shortcut menu, click Empty Recycle Bin.
8. Restart your computer.
9. Go into Add/remove programs and run a repair on itunes, this will rebuild the folders that you just deleted from the program files.
If this does not work for you please post any errors that you receive
I did all this but I still cannot uninstall, change, or repair. "The error msg is: The installation source for this product is not available..."
Now I am without iTunes amd canno sync my iPod or do anything else with MS Outlook.
Help? Thanks, Tom

The older version of iTunes cannot be removed..."
I still cannot uninstall, change, or repair. "The error msg is: The installation source for this product is not available..."
Not the most common errors messages to get with this sort of thing. But it looks to most likely be trouble with your existing iTunes installation configuration information.
Unfortunately, this sort of trouble has gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove".
Quit out of CleanUp, restart the PC and try installing iTunes again. Does the install go through properly now?
(If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.)

Cannot upgrade iTunes or Aperture - suggestions please

I find I cannot install the latest upgrades for iTunes (7.3) or Aperture (1.5.3).
iTunes behaves as though all is well throughout - it simply does not actually update and keeps pointing me to the update I have already used. Aperture (which is my key application). presently running 1.5.2 happily trashes any attempt to install the update to 1.5.3 by anouncing that the update requires Aperture 1.0 to be present. I have never had any problems updating either in the past - Aperture came as the 1.5 demo, which I purchased and then upgraded to 1.5.1 and 1.5.2 without any issues.
This problem has occurred under OSX 10.4.9 and 10.4.10. I have tried repairing and verifying disk permissions etc.
iMac 24 Mac OS X (10.4.10)

Have you moved or deleted the /Library/Receipts/ folder or its contents? If not, locate the receipt(s) for Aperture and drag them out of the Receipts folder. You can put them in the Trash (but don't empty) or on the Desktop. Then try the updater again.
Are you using Software Update? If so try downloading the standalone updater directly from Apple (http://www.apple.com/downloads/).
Check the Aperture forum also for possible help.

Cannot upgrade iTunes to 11.2.2 and cannot sync my iPhone 4 without iTunes upgrade?

I can't sync my iPhone 4 to my MacBook anymore. I get an iTunes message that I need to upgrade but my system check says I have all the upgrades. I tried to download iTunes 11.2.2 but my Mac can't handle it (OS X 10.5.8). Am I stuck in a 'Catch 22' here? Is this related to upgrading the phone to 7?

The issue is your Mac's version of OS X is too old. (Thank you for posting it!).
The current version of iTunes (11.2.2) requires at least OS X 10.6.8 to run. (The current version of OS X is 10.9.3.).
If your Mac is too old, you may have an issue. You might consider upgrading your Mac if you can. At a minimum, you would need to purchase Snow Leopard (OS X 10.6, sold below), and then update it to OS X 10.6.8.

Upgraded itunes won't open at all.

No error messages, just the little egg timer before....nothing happens. Everything worked ok with the old itunes pre upgrade this morning.
I am no techie so please help in idiot proof language!!!
Windows XP.

This may not help, but the first thing I'd suggest is to get a good antispyware checker and give it a go at your system. Some recent spyware has been reported by other users to shut down iTunes or prevents it from launching. From user reports, Ewido seems to be the best at catching it. You can download a free version of Ewido here.
If that doesn't turn up anything, search for the iTunes.pref file and move it out of it's folder (note it's location before you do so you can put it back if it doesn't help and you want to get all your prefs back), then launch iTunes again and see if it will then run successfully.
Hope this helps.

I upgraded itunes software and it synced all of our iphones in our family. We are now all receiving each others texts. How do we unsync each others phones?

All of our phones got synced together after doing an Itunes upgrade on line. We are now receiving all of eachothers incoming and outgoing text messages. How do we unsync from each other's phones?

I cannot upgrade itunes 10.1 or higher on Windows xp. I get the file 'C:\...AppleSoftwareUpdate\' is not a valid installation pkg for the product iTunes. Try to find the installation pkg in a folder for which u can intsall iTunes. Can't find folder. Now ?

This is getting frustrating, it won't let me upgrade. I get to a certain point where it tells me iTunes.msi is not a valid installation package for the product.
What do I need to do? I have bought a new Ipod & I have to update before I can download to my Ipod.

Cannot install iTunes 10.7 - keeps corrupting all my devices and usb drivers

I've had no trouble with iTunes for years, but cannot install iTunes10.7
Last iTunes running was 10.6.3.25
I'm running Win Vista 64 bit, with all windows updates current.
Last attempt:
Reboot computer (administrative access)
Downloaded iTunes 10.7 exe file
Closed all programs, including my firewall and anti-virus.
Uninstalled iTunes.
Removed appdata\Local\Temp folder
Installed iTunes 10.7 file
after the iTunes install runs quite a while, computer reboots by itself (no messages)
on boot-up, most device drivers are now messed up, including DVD devices=not seen
The only way for me to recover is to do a system restore to before the iTunes installation.
This has been going on for a few days - any ideas??

after the iTunes install runs quite a while, computer reboots by itself (no messages)
on boot-up, most device drivers are now messed up, including DVD devices=not seen
That's suggesting a device filter conflict in the registry.
I'd try the following document:
iTunes for Windows: Troubleshooting CD issues caused by device filters
(Although the document doesn't mention USB devices, they can also be taken out by a filter conflict.)

Cannot upgrade itunes due to error " c:program files|quicktime h264"?????

I just got myself a brand spanking new ipod, my husband has an older nano and uses itunes our computer. Itunes did not recognize my new ipod and said i had to upgrade to version 9. but when i try to download the upgrade i get an error message saying ERROR WRITING TO FILE: C:PROGRAM FILES\QUICKTIME\QTSYSTEM\QUICKTIMEH264.RESOURCES\NL.LPROJ\QUICKTIMEH264LOCALIZE DQTR.VERIFY THAT YOU HAVE ACCESS TO THAT DIRECTORY.
what the **** does that mean??? ive been on the computer all day dying to use my new ipod, have uninstalled itunes and quicktime but still it gives me the same error message. can someone please help, im going crazy, im desperate!!!!!

Yeah, there's anothe workaround we can try ... it doesn't fix the damaged files/folders, but it convinces the installer to ignore them and create new ones (instead of getting hung up trying to remove and replace the damaged ones).
In My Computer, open your C drive.
Open the "Program files" folder.
Open the "QuickTime" folder.
Open the "QTSystem" folder.
Open the "QuickTimeH264.Resources" folder.
Rename the "nl.lproj" folder nl.lprojOLD.
Now try another install. Does it go through properly this time?
