"Files shared by these updates has no valid signature" How can I download I-tune software update

I have a problem with installing the version 5 of the I-Pad software. It says "Files shared by these updates has no valid signature. It will not be installed.
Thanks,
Annie

Which "software updates" are you trying to download? For iTunes? iPod Nano? Did you download the Windows version?

When downloading updates for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed.

When downloading updated for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed. If I don't get that message I get a message saying that the download was unsuccesful and that in order to download I need to go to tools and then select dowload only. Please help I really want to update my iphone!

Thanks for helping out, but I already tried these steps.
I even tried this on a iMac with similar results. The only difference was that the errorcode was called 2001 instead of 21.
Today I took the phone to www.iphoneambulancen.dk. A guy (in Aarhus, Denmark) that specializes in iPhone repairs. I figured, that given his occupation he'd seen most errorcdes. Two hours later, he called me back, and told me that he had replaced the battery.
So, it turns out that a broken battery can cause this behaviour.
But thanks again

The file name only has 6 characters and I'm not sure what the .mod format is. So that's why they are not seen by the iPad.
Another way to transfer. You can use a USB flash drive & the camera connection kit.
Plug the USB flash drive into your computer & create a new folder titled DCIM. Then put your movie/photo files into the folder. The files must have a filename with exactly 8 characters long (no spaces) plus the file extension (i.e., my-movie.mov; DSCN0164.jpg).
Now plug the flash drive into the iPad using the camera connection kit. Open the Photos app, the movie/photo files should appear & you can import. (You can not export using the camera connection kit.)

HT1414 How do I download iOS 5 Software update?

Please how do I download iOS 5 Software update if I'm not ready to update via iTunes?

I have a job, so I don't hang your every word as soon as you post a reply to a thread in which I've participated. Now I've read your other post correcting the fact that I put 6.0.2 as the latest version of iPhone software I won't refer to the version specifically any more.
So, is iOS 5 available for download?
I find you very aggresive in your approach and if it continues, I will more than likely only ask questions on here rather than trying to assist others.
I have better things to do and I'm just trying to help.

If Facetime is not present on the phone you have, you cannot download it. The model of phone you purchased cannot have Facetime on it, period.
There is nothing to be done to download it - it's not possible.

The hard disk of my xServe is almost full and I need to delete the old Apple Software Udates that it contains (some of them are from 2005!!)

Thank's in advance from Spain.

You could try what
s in <http://discussions.apple.com/message.jspa?messageID=9289958#9289958>, or, as this is a new setup which isn't in use, you could just nuke the system and reinstall and this time use the correct DNS name.

Here's how to reinstall iTunes:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
Depending on your iPod model and iOS you can also update "Over the Air" by going into Settings/General/Software update. You'll need a Wi-Fi connection to do this and your iPod has to be connected to the adapter.

TS2446 Even after resetting password, I still get message "your apple id has been disabled. How can I download new apps?

Even after resetting my password, I still get message "your apple id has been disabled". How am I suppose to download updates or make purchases?

Try logging out of your account on the iPad by tapping on your id in Settings > iTunes & App Stores and then log back in and see if that 'refreshes' the account on it
If having changed your password and having logged out and back in doesn't fix it then you might need to contact Apple : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page

How can I ignore or skip Software Update?

Hi
Yesterday , I've updated my bb z10 to 10.1 and in Software update step I can not skip this part .
Also only show Cheking for update without doing something.
I would know If I reload this device my bb z10 remain in os 10.1 or going back to os 10?
this is my situation and also I can not go back or next step , what I have to do?

You can reload your device OS using BlackBerry Link. If you do so, you'll be reloading the past OS you had and not the new one. You have to specifically accept the new OS in order to load it otherwise you'll get the previous version you had on your phone.
I hope I've answered your question. If not, please post back with more information.
- If my response has helped you, please click "Options" beside my post and mark it as solved. Clicking the "thumbs up" icon near the bottom of my response would also be appreciated.

How can I cancel the iOS software update?

For some reason, iOS 6 has decided to download on my iPod Touch through WiFi. I didn't request it, nothing is set to automatically update in the Touch settings, or iTunes. It seemed to start downloading when I synced the Touch. I've disconnected the Touch from WiFi temporarily. How can I cancel the download, or will there be an option when it's done downloading to cancel the install?
Thanks for any help...

I had the SAME problem & it was incredibly frustrating. Having WiFi disabled for days caused me to eat up A LOT of my data plan. It is total BS that there is no way to cancel an OTA download. And it is total BS that no one can get ANY help on this issue. There should be a way to cancel or at least downgrade if you don't like the newest iOS.
So, since Apple won't let you downgrade if you went ahead & installed it, and Apple won't help AT ALL if you don't want iOS 6, I had to figure it out myself. Here's what I did....
The stupid iOS 6 update that nobody wants needs a certain amount of free space in order to download & install. I had started the download & disabled WiFi like you did, so the download was paused. While it was paused, I set my video camera to record & it sat there & recorded for like 2.5 hours (ugh) before it finally took up all the space on my phone. Then, I went back in & enabled WiFi & checked the piece of junk iOS 6 install & it now said it couldn't download b/c there wasn't enough space.
I figured this solution still s ucks b/c now I can't download any apps or take any more pics or vids. About 30 minutes later, though, I went back to the horrible iOS 6 download & a message popped up saying there wasn't enough space. When I hit "OK" or whatever to clear the message, the screen had reset & gone back to the "download & install" button. FINALLY I was able to stop the download & installation of iOS 6. THANK GOD. I want nothing to do with it, and there is NO WAY Apple is taking my Google Maps or YouTube.
