HT201210 Unable to update iTunes or Quick Time. Message: invalid signature

I am unable to update iTunes because I receive the message "iTunes has an invalid signature and will not be installed."

"+unable to delete older version of quick time" "The feature you are trying to use is on a network resource that is unavailable" "enter an alternate path to a folder containing the installation package 'Quick Time.msi'".
With those symptoms, download and install the Windows Installer CleanUp utility from Microsoft:
http://support.microsoft.com/kb/290301
Now run the utility ("Start > All Programs > Windows Install CleanUp"). In the list of programs that appears in CleanUp, select any QuickTime entries and click "Remove".
Quit out of CleanUp, restart the PC and try another QuickTime install. Does it go through properly this time?
THIS WORKED FOR MY SYSTEM. I have now reloaded both iTunes and Quick Time. THANKS

Unable to install itunes 7.5 becasue of invalid signature

I just bought a new iPod touch and it is my 3rd iPod.
i have been trying to download the lastest version of iTunes and everytime i try to download it, it says "unable to download itunes 7.5 becuase of invalid signature."
please Help. i have no idea what to do.

I can't help you, but I am having the same error message : 1921. I bought a new ipod nano and cannot use it because of this. Installation seems to be going fine until it stalls at the part where it says Status: Stopping Services. I don't have dial-up so I don't think that's the issue. I have contacted Apple support and all they can say is to look on the discussion board, continue to look on the help page, and read an article that says this happens when you try to install itunes 5, and that it could be that Windows Management Istrumentation service isn't running on your computer OR that Norton Interntet security 2005 is running on the computer. To resolve this issue, install itunes 5.0.1 or later. This makes no sense because I am trying to install itunes 7.5.
I have tried to uninstall itunes and I get another error message: -1603 Fatal Error During installation. consult Windows Installer Help(Msi.chm) or MSDN for more info. I have tried doing this, but I really don't know much about computers. I'm not really sure if I am tring to remove itunes correctly. I am just so frustrated and hoping that someone out there has a solution to this particular problem.
Any suggestions would be greatly apprectiated!

Unable to upgrade itunes or Quick Time

I recently transferred all my data and programs to a new hard drive. Since then I have been unable to run itunes. The message "This action is only valid for products that are currently installed". When I try to delete itunes so I can reinstall it I get the following two messages:
"The feature you are trying to use is on a network resource that is unavailable
The installation source for this product is not available. Verify that the source exists and that you can access it".
Any ideas.

Has anyone been able to successfully update the iTunes 10.6.3? I keep getting the same error message each time i try: "Errors occurred while installing the updates. If the problem persists, choose Tools> ..." which I've done repeatedly with no luck...

Try updating your iTunes using an iTunesSetup.exe (or iTunes64Setup.exe) installer file downloaded from the Apple website:
http://www.apple.com/itunes/download/
Does that go through any better for you?

Unable to update Itunes,Itunes 64.MSI problems

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 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.
The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if one component won't install normally.

Perhaps your ISP is lying about Google's address?
Since there is no Mac version of Chrome, it's unlikely that Google is trying to force you to use that Maybe they're hoping you'll write it?
Try http://74.125.19.99/ and see how that works (that's one of the addresses that Network Utility shows me for www.google.com).

I checked my Services console and Bonjour was started. I can also stop and start it without issue. I searched for these errors, but most of what I found was trouble getting the Bonjour service to start and as you can see, this is not my issue.
I have also tried to update iTunes with Bonjour stopped and disabled and with my Eset NOD32 Antivirus software disabled, but neither of these steps made any difference. I do not have a third-party firewall on my PC, but I am using Windows firewall. I have also tried disabling the Windows firewall, but this made no difference.
Any help would be appreciated.

ITunes and Quick Time upgrade 9.0.2 error downloading and installing

Hi,
This morning I recived notification that there is a new update for iTunes and Quick Time. While downloading and installing this upgrade 9.0.2, I received the following error:
An error occurred during the installation of assembly "Microsoft.VC80.CRT, version= "8.0.50727.4053" type="win32", publicKey Token="1fc8b3b9a1e18e3b", process or Architecture="x86"', please refer to Help and Support for more information. HRESULT: 0x800736B3.
What the heck does that mean???

I received the same error and spent roughly an hour and a half troubleshooting with the Apple Customer Support before I was told that it was a Windows or Lenovo manufacturer issue -- something to do with a registry key -- and that this was outside the realm of Apple Customer Support.
If you are able to resolve it, I would be interested in knowing how.

Help to install iTunes and Quick Time please!

I really hope you can help me. I have been working my way through this forum for around 5 hours today. I have tried a number of your suggestions and have made some progress.
- My iTunes hasn't been working for some time. I tried to uninstall it and reinstall a fresh version but it wouldn't uninstall.
- So following forum advice, I downloaded and ran Windows Install Clean Up and also did a manual deletion exercise. This left a few odd files that wouldn't delete.
- I have downloaded iTunes 8.2 but it won't install. I get an error message: "error writing to file: c:\programfiles\commonfiles\apple\mobile device support\syncservices\schemas\calendars.syncschema\contents\windows\calendars.ex e Verify that you have access to that directory" and eventually I get a message telling me that iTunes needs Quick Time.
- I also downloaded the stand alone version of Quick Time. When trying to install it I get the error message "error writing to file:c:\programfiles\quicktime\pictureviewer.resources\ko.1proj\pictureviewerlo calized.dll Verify that you have access to that directory"
- I can confirm that I am the only user of this computer and I have administrator rights.
- I have installed the latest Microsoft updates.
- I have restarted my computer about 3 times, after each major thing I've tried.
Totally Stuck Now!
I did read a suggestion about using a Microsoft fix but it involves going into the registry and I don't have the confidence to do that, I don't really know what I'm doing at all, I'm just following my nose!
When my computer starts up CheckDisk says "correcting error in index $0 16208" and after correcting and sorting it says "an unspecified error occurred".
Please help!!

It sounds as though the file referred to in the error message is corrupt and Windows cannot read it.
Try running a disk check. If it finds and fixes errors, try reininstalling. If not it it doesn't work, go on to the next step.
Try renaming c:\programfiles\commonfiles\apple\mobile device support\syncservices\schemas\calendars.syncschema\contents\windows\calendars.ex e as ...calendars.old.
If Windows will not allow that, then rename the containing folder.
This should allow the install to proceed as it will not see the corrupt file.

Unable to update iTunes - missing iTunes64.msi

Unable to update iTunes - each time I get error message: "The feature you are trying to use is on a network resource that is unavailable." It cannot find the installation package "iTunes64.msi". Have tried various methods found on Apple Support to no avail. I think it might be something to do with uninstalling old versions of itunes - I can't seem to do this either, even using the Microsoft Fix it programme. I do not use a network. I use an external HD to save music files but with this plugged in the problem persists. Any help would be much appreciated! It's driving me mad!!

IPhone 4.0.1 unable to update iTunes/AppStore Billing Information (county)

+*iPhone 4.0.1 unable to update iTunes/AppStore Billing Information: Prevents Purchasing/Installations*+
++When accessing the AppStore I am prompted to update my iTunes billing information. This process generates a loop when selecting the county and will not update. This prevents purchases or free downloads from the AppStore.++
Details:
+I have a new iPhone 4. When I received it I activated the phone, restored from back-up and updated the software to 4.0.1. After the software update was complete I tried to install Free and Purchased applications from the App store. I cannot install any free or purchased iTunes application, music, or video.+
+*I received the following messages:*+
*[Verification Required]*
+Before you can make purchase, you must tap Continue to sign in, then verify your payment information.+

*[Sign in Required]*
+Tap Continue and sign in to view billing information.+

+County information is required to calculate the applicable sales tax on your purchases. Choose the county where your billing address is located.+
County:
Cancel (Done)
I select the county and select done the screen loops for the county information.
*Things I have tried:*
- Updated billing information via iTunes on the Mac (Updates successfully) - but will still prompt for updates on the iPhone.
-Restarted iPhone (same)
-Erased iPhone and activated as new without restoring from backup (same)
-Contact iPhone support (no other advice then what happened here the first time) the second attempt at support has resulted in a call with iPhone and iTunes Support.
I will post back my findings, but has anyone found a solution.

The only difference I noticed was that the card that kept looping was a visa check card, verse a credit card (mastercard). I am not sure if there is a problem within the iPhone application. I don't believe this to be an iTunes or App store problem because the account profile will accept the card information via a computer. This problem seems to be within the address verification process the iPhone/app store does only on the iPhone platform. Apple support and iTunes support seems to be clueless. My original post is the only way I've gotten it to work.

After replacing the hard drive on my G4 Powerbook and reinstalling Tiger I am no longer able to synch between itunes and itunes, it seems that the software on the ipod is of later date than itunes and I am unable to update itunes to the state prior..

After replacing the hard drive on my G4 Powerbook and reinstalling Tiger I am no longer able to synch between itunes and my ipod (Classic 160gb) it would seem that the software on the ipod is of later date than itunes and I am unable to update itunes to the state prior to the original harddrive's failure for Tiger OSX 10.4.11
Any ideas on the subject would be most helpful
Thanks in advance
Dingoh

The last security update released for Tiger users was the 2009-005 update. The latest version of QuickTime is 7.6.4. The last version of iTunes that can run on Tiger is 9.2.1, because 10.0 only supports Mac OS X Leopard and later.
So, are you on version 9.2.1?
Was it Tiger or Leopard you had on the drive before?
iTunes 9.2.1 download...
