"invalid signature" while updating to 7.6
I have tried SEVERAL times to update to iTunes 7.6 on my PC, each time I get a little further in the process, but I still get a window that says iTunes has an invalid signature and will not install. I have updated my ASU and deleted my temp files. What else can I possibly do? I have purchases that will not download because I cannot update to 7.6! Any help would be greatly appreciated!
Follow this process, it helped me get most of the way there:
1. Open control panel
2. double click security center
3. click internet options link at the bottom
4. click advanced tab
5. scroll down until you see the Security sub-heading
6. make sure the "Allow software to run or install even if the signature is not valid" check box is checked. (third check box under the heading)
7. click apply
8. click ok
9. download itunes and install

I get an error "iTunes QuickTime" has an invalid signature. The download has been removed. When trying to update from version 10.1 to 10.2.2. I have a Toshiba laptop running Windows 7 OS. I have tried repairing all the Apple software on the laptop. What do I need to do to get this updated?
I have not had this problem before but the latest update to iTunes + Quicktime, offered today, puts me in the same situation.
The web is covered with reports of this issue over the years, always "iTunes + Quicktime has an invalid signature", but nothing I can see which is a good fix for the problem.
Tried chkdisk, install manually doesn't work, the installer just keeps trying.
Tried installing QT 7.6.4 independently from the Apple download page, that didn't help either.
If this is so prevalent, why isn't there more on the main Apple site about it? -
Phone does not restore from icloud (invalid device while updating mme delegate account)
Hi
When restoring an iphone4 I get to the part that says restore from icloud, then enter the user details (if you get them wrong it tells you) then it moves onto the Terms and Conditions page which you then click agree. At this point I either get "there was a problem connecting to the server" or "invalid device while updating mme delegate account".
Help ....
Any ideas pleaseSorted it by clicking the home button and choosing start again, the phone then erased its self and the next time it started the restore process worked fine

HT3529 invalid device while updating mme delegate account
What does, "invalid device while updating mme delegate account" mean while I was resetting up iphone?
that error is typically in referance to trying to restore from a back up created on a higher software version, set the device up as new without signing into your appleID, update, then erase all content and settings to get the set up assistant again.

Invalid signature so update to 11.01 wont load
When I try to update to Itunes 11.01 Iget a reply "Files shared by these updates " has an invalid signature. It will not be installed. I am trying to update from 10.6.3.25 to 11.0 but the files refuses to go past initial download. Any one know what I can do.
I'm using my PC on Wndows 7 for ITunes.Hi Mark
You say everything is up to date? And you have tried reinstalling all the CC apps? Is Windows also fully up to date? Hmmm... That could be tricky.
What version of Windows are you using? Have a look in Task Manager > Processes and see if 'CEPServiceManager.exe *32' is listed as running?
If not, I don't know where it would be installed from, and we'd need someone like Chris Cox to join the thread to tell us, but my guess is that it would install along with the CC Desktop Application Manager. Windows 8.1 can be problematic, and a bit fussy about the order of things, and it is definitely worth adopting best practice when installing your CC apps. That means restarting your computer, and right clicking the Desktop Application manager and running as Administrator.
How many CC apps are you running? If just Photoshop, Bridge, Expansion manager etc. then - and I hate to say this - perhaps have another go at reinstalling, but run the Cleaning tool after uninstalling.
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
Try some other Extensions before the Tony Kuyper's TKActionv3. GuideGuide is a favourite of mine, as well as Dmonzon tools, and maybe Russell Brown's Flypaper Textures.
I have to say that I have had problems with the CC Extension Manager a while back, but simply reinstalling just the Extension Manager fixed it. Perhaps CEPServiceManager.exe *32 installs with Extension Manager? Heck, maybe start with just trying that before reinstalling all your CC apps.
If you are still stuck, I'd risk sending Chris Cox a PM, but not until you triple check that your video card driver is up to date from the card maker's website.
Good luck, and be sure to let us know how you get on. -
After a complete crash of my iPad 3 (WIFI only) because of updating to iOS 7.03, I try to restore my config from iCloud.
I managed to get into the settings assistant and enter my Apple-ID (which is valid as checked via iTunes).
But then I see the error message "Apple ID cannot be created - invalid device while upgrading mme delegate account".
I have no clue what the mme delegate account is but need my data back.
Any suggestions?All you need to do is restore the iphone in itunes as new
and then set up as new
after this is done
then you can restore from itunes back up with out any error!!

"Invalid Signature" preventing update to iTunes 10.3 in Windows XP
When I try to update iTunes to 10.3 on my Windows XP system with the Apple Software Update application, I get a pop-up box saying "iTunes has an invalid signature. The download has been removed". This happens whether I select install or change to download only. How do I get around this problem?
Follow these instructions to completely remove Apple software
http://support.apple.com/kb/HT1923
Then use free Ccleaner to repeatly repair your registry until it's fixed.
http://www.piriform.com/ccleaner/download/standard
download iTunes again from Apple.
http://www.apple.com/itunes/
If you have 64bit Vista or Windows 7, look for the seperate download of iTunes for that further down the page.
Once installed, use the Apple Software Update under your Start Menu to fully update all Apple components.
Your content will remain on the drive in the Music > iTunes Folder, nothing is deleted.
You should be making backups of your content regularly, either through iTunes or via copying the iTunesFolder in your Music folder to a external drive.
Windows is notorious for having "other" issues that make it unstable, we as volunteers helping others can't always resolve those issues. -
Invalid signature prevents update, unable to install without it
When I try to install Itunes 10.1 from Apple software update on my Windows 7 64 bit machine, I get an "invalid signature" message at the end of the QuickTime downlay and the download aborts. When I download Itunes64Setup.exe from the website, it aborts within a second or two.
I have tried every conceivable solution on this and other websites to no avail (deleting and reinstalling using Windows Install Cleanup and Revo Uninstaller, deleting files directly, changing the options in Internet Explorer, updating Software Update to the newest version, and too many others to mention). I even reinstalled Windows from the DVD. I even spoke with a friend who works as a "Genius" but nothing we tried
I have been able to install QuickTime 7.40 from the standalone file, which gets me back Application Support and Software Uptdate, but Software Update does not work at all and but there is no way to get Itunes back, Since I deleted the prior version of Itunes, I can no longer sync my ipods, Ipad or use my Mobile Me account, no less upgrade to the OS when it comes out next week. I am desperate.Well, yours is the first I've heard this happening with a wired connection! Had to look up FIOS, no one else has mentioned a fiber optic connection, either.
It's no consolation to YOUR dilemma, but millions of folks are getting the download OK and it DOES have a valid signature.
I've read posts about resetting security certificates, changing router settings, yadda yadda yadda. Seriously it will probably be less time spent trying to troubleshoot, if you just get it the setup files from a friend who has successfully installed itunes/QT. -

HT201413 Invalid signature when updating itunes and icloud, cancels update?
Apple software update cancels because of invalid signatures, what setting do I need to change?
That one suggests the installer has gotten 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? -
