Itunes won't update because of a bad signature

I am updating a Sony Notebook to update Iphone 5 and I tunes, on system but not updated, will not download because of a invalid signature.

I no longer have this problem. I saved I tunes to the computer, closed everything and ran the program from my computer. Worked perfect.

Itunes won't update because it doesn't recognize my password

I changed my itunes password when Apple began requiring a capital letter and number. But now my iphoto needs to be updated because the version I'm currently using isn't compatible with my imac. However, it says it can't update it because my password is different from the one i originally bought the app with. How do I update it?

Itunes won't update because of Bonjour, what should I do?

I need to update my Itunes and every time I try to at the very end a message comes up saying that my computer couldn't remove the older Bonjour.
I need help! What should I do?

at the very end a message comes up saying that my computer couldn't remove the older Bonjour.
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 Bonjour entries and click "Remove", as per the following screenshot:
Quit out of CleanUp, restart the PC and try another install. Does it go through this time?

You can't all apps are tied to the apple id that was used to purchase/download it.

Itunes won't "read" because it was created by a newer version of itunes

I just updated my operating system finally and when I try to open itunes I get : itunes won't "read" because it was created by a newer version of itunes.

This error prevents iTunes from launching. The library file was modified to work with the newer iTunes version, so it is no longer compatible with the previous version. The good news, however, is that Apple does backup the iTunes library file into a subdirectory that you can use to revert back to the previous version.
To recover a previous version of the iTunes Library.itl file, use the following steps:
Open up your My Documents\My Music folder.
We will first backup the current version. Rename iTunes Library.itl to something like iTunes Library.itl.bak.
Go into the My Documents\My Music\Previous iTunes Libraries folder.
You may see several files that start with iTunes Library and have a date included in the name. Copy the newest file in the folder.
Go back to the My Documents\My Music and paste the file from the previous step.
Rename the new copied file to iTunes Library.itl.
Your library should now be restored to the previous version of iTunes, and you should no longer receive the message.

My iTunes won't update on my computer. I have windows vista. I can open iTunes and when I click "check for updates" it asks if I want to update to iTunes 11.1.5 and I click "Download iTunes" but then nothing happens. What's wrong?

My iTunes won't update on my computer. I have windows vista. I can open up itunes and when I click on "check for updates" it asks if I want to download iTunes version 11.1.5 and I click "Download iTunes" but then nothing happens. Sometimes uptop the loading bar will appear but for only a split second. I have tried restarting, shutting down, I cannot figure out why it won't download. What's happening and how do I fix it?

Try updating using an iTunesSetup.exe (or iTunes64Setup.exe) installer file downloaded from the Apple website:

My iTunes won't update, it starts to install then just says it can't. I decided to try uninstall it but it won't even uninstall anymore, there is some type of ERROR going on. I tried to just install iTunes from the website and that won't even work.

itunes won't download because something about "mobile device not authorized?"

Hi buckirich,
Thanks for using Apple Support Communities. It sounds like you may need to restart the Apple Mobile Device Service. This article has instructions for doing this:

http://support.apple.com/kb/ts1567
If that doesn't resolve the issue, I would recommend trying a thorough uninstall and reinstall of iTunes as described here:

TS1717 itunes won't start because it says the folder was made in newer version, what should be done?

itunes won't start because it says the folder was made in newer version, what should be done?

If you haven't deliberately tried to downgrade iTunes then it is possible the library is corrupt. This approach should work.
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.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

ITunes won't update, unistall or re-install.

iTunes won't update or unistall. When I try, it says the installer source doesn't exist. When I tried to just reinstall it fresh, it says the old versions of Bonjour, iTunes and Quicktime can't be removed. Any solution for any of this?

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. (The results from mydigitallife and Major Geeksare worth checking.)
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 anyiTunes, QuickTime and Bonjour entries and click "Remove".
Restart the PC, and try another iTunes install. Does it go through properly this time?

Itunes won't update, ipod unusable without it

I have an ipod touch. I have been really good about keeping my itunes up to date. The last version I updated to was early this year. It keeps telling me I need to update but that it failed to update after download and that I need to manually install.
I plugged my ipod in and it asked me to update the ipod software so I did. Then it tells me that the ipod won't work unless I have the 10.0.1. But when I go to itunes and download itunes 10.0.1 it downloads but won't install and tells me I have an invalid drive F:/. I don't even have a drive F. I can't use my ipod now, I turn it on and I have the picture of the ipod being plugged into itunes. But itunes won't update. Nothing online or in any thread I have found has given me a solution. I am very frustrated. Is there anything I can do? Or do I need to uninstall itunes and lose all my music and apps?

I just put a flash drive into a USB port and then it started the install and when it asked where I wanted to put it I changed it from drive F to C.

HT4623 phone is locked with a passcode and I don't have the passode, it says connect to itunes, and itunes won't connect because it says to enter passcode on phone. The device also does not show in itunes so I can't restore

iphone 4s is disabled. It says connect to itunes. Itunes ays could not connect because phone is locked with a passcode and to enter passcode on iphone before it can be used with itunes, but I can't enter the passcode because 1) don't know it 2) it's disabled. The device also does not show up in itunes, so how can I restore the phone or unlock it?

Same answer as last time you asked the exact same question:

I have a 5 year old MacBook running OS X v10.5.8 Of course Apple does not provide an OS update and then other software apps won't update because the OS is obsolete. Is there a way of upgrading the hardware so the software can be made current?

The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a early 2008 iMac supposedly limited to 4 GB and noticed an improvement.

My iTunes Won't update apps

My iTunes Won't update apps when i click check update it say"your iTunes library is up-to date"
awhen i check update From iPhone the it update all apps which are out dated

It sounds like you've already done the things that would fix most iPhones.
You can try restoring your iPhone.
If that doesn't do it, try contacting Apple through Express Lane. They may be able to gather some aditional logs and pinpoint the exact problem.
