Updateing to i tunes 8.2.1 error message wont install
help..trying to install itunes 8.2.1 but get warning message that it does not have a 'valid signature' and will not be installed.
i was hoping that having the most uptodate itunes version would assist in finishing downloading a pop video that wont complete...just get error code 8008
any ideas would be great
thanks
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?

When I launch I-Tunes I get an error message saying that it can't run because msvcr80.dll is missing and then another error message saying that I have an error 7 (Windows Error 126). I tried uninstalling I-Tunes and re-installing but it did not fix it.

In the iTunes window, when I update my nano ipod, I get an error message "User ipod cannot be updated. The disk could not be read from or written to." How can I overcome this error message.
Hello there dilip77707,
It sounds like you are getting this error message that your iPod cannot be read from or written to when you are trying to update your iPod Nano. I recommend the troubleshooting from the following article to help you get that resolved. Its pretty straight forward, just start at the top and work your way down as needed:
'Disk cannot be read from or written to' when syncing iPod or 'Firmware update failure' error when updating or restoring iPod

I cannot update my ipad2 to ios5. Updating through iTunes on pc Windows Vista, Error message reads "cannot connect to iPad Software Update Server. Tried resetting network settings, still not connecting. Tried updating iTunes, still not connecting.
Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

Having problems with Bridge shutting down after saving photo in PS Cs5,,,,,,,,, Also when i attempt to update either PS or bridge get an error message in Adobe application manger "Error loading updater workflow"
Sorry for the late reply. My email firewall has become a little over zealous & sent a lot of my emails straight to my junk email folder, so I have only just now discovered your reply in my junk mail folder.
The only "don't open files exceeding xxx megabytes" instruction I can find in my Prefs, is in the Bridge Prefs for Thumbnails, & mine is set at 1000mb. The biggest files I handle are bigger than 200mb so I should be able to open a few, not just one.
However, this doesn't explain why I can open a psd format file of 180mb, close it, but then can't open a RAW format file of only 26mb immediately after.
I can open the RAW file only if I restart my computer - very annoying!
However, thanks for the advice about the video card & memory.
So, I'm still stuck as to what the issue is. -
can't update new version of itunes due to error message saying invalid si
That 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:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer? -
Safari won't load and I can't update my software, ie., I get an error message. What can I do to fix this?
You can't install Safari 3 on your 10.3.9 OS.
You must use the DVD installer to re-install the older version of Safari found on it.
You can update your operating system buy purchasing Tiger (10.4) and get a more modern version of Safari. -
When trying to download updates for Pages etc, I get this error message: There was an error in the App Store. Please try again later. (20)
Hello almauck,
Thank you for the details of the issue you are experiencing when trying to update Pages on my iMac.
I recommend signing out of the App Store and signing back in and then trying the update again:
Sign out
Choose Store > Sign Out.
Sign in using an Apple ID
Choose Store > Sign In, or click Sign In in the Quick Links section. The Quick Links section is located in the right part of the window shown when you click Featured, Top Charts, or Categories in the toolbar.
Enter your Apple ID and password, and then click Sign In.
Mac App Store: Sign in and out

After moving from Canada to the US, getting a new iPhone 5C, and restoring my backup from iCloud, I can't update my apps. I get an error message that my account is not valid in the Canadian App store and I must change to the US store. How do I do that?
Change here:
Settings > iTunes & App Stores > Apple ID: > View Apple ID > Country/Region.
You must have a verified billing address & be located in the country whose store you are trying to use. -
Error message after installing 10.8.2 update
After installing the osx 10.8.2 update the mok resrtarts and give a error message: "the update could no be installed" or so. As I look up in the system info the update appears al isnatlled. Why?
I'm another user with same issue, started right after the upgrade, appears consistently with login/out, sleep/wake, rarely otherwise.
? some launchd process calling usereventagent which then crashes
Application Specific Information:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber length]: unrecognized selector sent to instance 0x5088002c7'
abort() called
terminate called throwing an exception
This is on a 2.66 GHz Quad-Core Xeon. No similar issue with my Air which I also upgraded to 10.8.2, so I suspect it's a launchd process installed by something which I and others have added that gets run at login and logout (and less frequently at other times). -
When ever iTunes updates, it ends up coming up with error message, iTunes did not install properly, please re-install iTunes, this is about the fourth time this has happened, end up having to take it to computer tech at a cost of $180, please help
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.

I have the current version of itunes, but when I go to update my ipod, I am getting an error message that says that it could not back up because the backup was corrupt or not compatible with the iPod. This is the first time trying to backup the iPod. I have authorized my computer. Still no luck.
Go to iTunes>Preferences>Devices and select the iPod backjp and click on delete and try again.

- Reboot the computer
