Can't update iTunes on my Pc with Windows 8

I have updated my iPhone 4 to ios7 via wifi because I was not able to update iTunes on my Windows 8 pc and update the iPhone by synching. Now however, my computer won't recognize my phone and says to upgrade iTunes.
When I try I keep getting the following error message -
"iTunes" has an invalid signature. It will not be installed.
When I try to just do a download, the same thing happens.

I called this problem into Apple and they solved it for me. The problem is in the downloader associated with iTunes. Skip that step and go to Apple.com and download the new iTunes softwere update (Version 11.1) directly. I did this and installed it successfully. After restarting the computer iTunes recognized my phone and all was well. Then I updated and installed the ios7 update without any problems. No charge. Full cudo's to Apple!

Can't install iTunes on new notebook with windows 8.1

First, sorry for my bad english, i hope you can understand what i am trying to say.
I got a new notebook and wanted to install iTunes. First it worked but then i needed to do a system restore because of a virus.
So iTunes was no longer on my notebook and i tried to reinstall it, but it does not work. I always get "try to install new, ERROR 7 (Windows error 5).
I searched through many communities and tried things like activating the Microsoft Frame Network or manual deinstalltion, restarting the computer, ...
Please help me

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

Can't Install iTunes on my laptop with Windows Vista...PLEASE HELP

I've received error messages every time I try to download iTunes. I've tried the troubleshooting steps on Apple's website but no luck.

Good lord ... a bit of an alphanumeric soup there ...
It's not clear initially which is the fundamental error here. But based on the fact that the 8007371b can be fixed by the System Update Readiness Tool, we might try a manual install of that first. There's information on how to do that in the *Information for Advanced Users* section of the following document.
[Description of the System Update Readiness Tool for Windows Vista, for Windows Server 2008, for Windows 7, and for Windows Server 2008 R2|http://support.microsoft.com/kb/947821]
Installing the tool will run the tool.
After the installation of the tool, restart the PC. Then go back to Windows Update, and attempt to stock up again on Windows Updates. Do they download and install correctly? If so, because you might be a reasonable way behind on updates, keep going back to Windows update until it stops offering you new updates.
Once you're stocked up again, restart the PC again, and try another iTunes install. Does it go through properly this time?

Can not update iTunes because I have iMac with 10.5.8 . How I will sync my iphone 6.0 with an older version of iTunes on my iMac???? There is no update for the software of my iMac and no update for the iTunes.... So how can I sync????

Requirements for iPhone 5:
Syncing with iTunes on a Mac or PC requires:
Mac: OS X v10.6.8 or later
PC: Windows 7; Windows Vista; or Windows XP Home or Professional with Service Pack 3 or later
iTunes 10.7 or later
The highest version of iTunes you can install is 10.6.3 which will not sync with the iPhone 5.

It's always a good idea to check the requirements before purchasing.
The person I spoke with at 1-800-MY-APPLE gave me totally different info...she said the iPhone 5 would in fact sync with the older version of iTunes and that I could restore from my previous iPhone 4 backup and also bring in my music that way. Hmmm....
I'm inclined to go by the published specs, but now I have to jump thru a bunch of hoops I wasn't expecting to.

If you go to iTunes on your computer click on the App Store and scroll all the way down . In the bottom right of the screen is a map logo. Click on that and then chose the flag for the country you want

I can't update itunes to 11.0.4 on windows 7

I can't update itunes to 11.0.4.
When I try to update a message pops up saying "the feature you are trying to use is on a network resource that is unavailable". The same thing happened with the last update. I had to uninstall and download the new version.
Every other update has worked on this laptop until then. I've just updated itunes on the other two laptops without any problems.
Any ideas?

I've tried again but it's still not working. This time a message appears saying iTunes64.msi file not found. Check the file name and try again.

Can't update iTunes

Every time I try to install iTunes 10.5 on my macbook pro, it gets almost to the end (blue progress bar moving along then stays at about 90% for a couple of minutes), then my entire computer crashes/shuts down. This has happened three times in a row. What can I do to successfully update iTunes so I can update my iPhone? Thanks!

1) Nope. I rarely even use QuickTime, unless it's to view a video I took with my digital. So I never really even updated unless the little notice opened up prompting me to do so.
2) Actually, when I try to uninstall, it's not in the add/remove window, but the uninstall link is in the programs menu. But when I do that, the InstallShield comes up, loads for a few seconds, and then nothing.
Also, when I try to open QuickTime by itself, I get this message:
"Your copy of QuickTime 7.0.2a63, QuickTime Player 7.0.2a63 has expired. Please visit www.apple.com/quicktime/download to download and install a new version."
I can't update iTunes without the latest QuickTime, and I can't download the latest QuickTime without installing iTunes, but it keeps giving me errors. I had circular dilemmas like this. =/

I can't update iTunes. It says the feature you are trying to use is on a network resource that is unavailable.

It says Click Ok to try again or enter an alternate path to a folder containing the installation package itunes64.msi in the box below
(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?
