"iTunes has a invalid signature" when updating to 11.1
I was trying to have iTunes updated to version 11.1 but It failed to download first before install, then I clicked download only and the message popped up saying "iTunes has a invalid signature". Why I keep getting this? and How can I fix it?
I'm running Windows 7 64-bit.

Unable to update iTunes. Get 'iTunes has an invalid signature. It will not be installed.' When I reboot, get message 'Apple Sync Notifier.exe entry point not found'
Please help...need to get newest update so I can activate my new IPhone4. ThanksThat suggests that the installer is getting damaged during the download.
I'd first try downloading an installer from the Apple website using a different web browser:

If you use Firefox instead of IE for the download (or vice versa), do you get a working installer? -

When I try to download the latest version of iTunes from apple.com, I get the message "Content was blocked because it was not signed by a valid security certificate."When I open iTunes and try to download the latest version there, I get the message "iTunes has an invalid signature. The download has been removed." I have also gotten an Internet Script Error stating that an error has occured in Line 0, Char O and that "Access is denied to images.apple.com/global/scripts/lib/iepngfix.htc." This problem has never occurred with earlier versions of ITunes. Anyone know how to fix this problem?
Are you downloading iTunes form an Apple website or somewhere else? If the answer is somewhere else, try downloading it from Apple. Click on iTunes in the black menu bar above and go from there.
Let us know what happens. -

When I try to download and install the latest software version of iTunes, this message occurs: "iTunes has an invalid signature. The download has been removed." Any suggestions?
You seem to have an iTunes problem and not an iPod problem. I suggest posting in the iTunes forum.
How areyou doing the download?
From Apple's site?
Via the Apple downloader
PC or Mac? -

I am assuming you are having difficulties installing the latest version of iTunes. Are you using a Windows PC or a Macintosh? Which version of Windows or OS X are you using? -
Error "itunes has an invalid signature". Will not install. Why?
Every time I try to update iTunes on my desktop computer I keep getting the same error message "iTunes has an invalid signature. Will not install. Why am I getting this message? and how can I fix it.
ITunes came with the new HP I purchased in 12/2013. I have had a problem only with updates. I thought about uninstalling on my desktop but do not want to lose my songs. Was hoping to find a better solution than uninstalling and then re-installing.
Any how would be appreciated.The error suggests some sort of corruption with the file you downloaded. Clear your browser's cache and download a fresh copy of the iTunes setup file.
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.
If you are running 64-bit Windows and the above steps haven't helped try installing the version of iTunes that can be downloaded from this support document. iTunes 12.1 for Windows (64-bit — for older video cards)

I normally do not update my iTunes, but after the iOS 7 release, iTunes 11.1 was required in order to download this. I attempted to update, but right as the download began to finish, apparently iTunes has some sort of "invalid signature". This was not a problem, but then I upgraded to the iPhone 5s, and in order to transfer my music, apps and contacts to my new phone, this became a problem. I tried to update both on my desktop and my laptop and both came up with the same response. Is there any way to troubleshoot this or maybe transfer these things another way? I would rather not manually enter my 500 contacts into my phone.

In your situation I would recommend the steps in the following article for troubleshooting iTunes. It may be necessary to completely remove and reinstall iTunes in this situation. Be sure to remove all of the components with iTunes in the correct order as outlined in the article before installing fresh.
