I have tried to download the update for itunes several times. Each time it get to the installation part and stall and then reverses and give me an erorr message. My current version when I open it, it says there is an error and I will not be able to download a CD into itunes, although I have completed several CD downloads.

Go to http://www.mozilla.org/en-US/firefox/new/ and download the full installer. Run the installer and you will be up-to-date. Sometimes the updater just gets in a weird state...

Hi again,
Helps if I give the correct link ! <br/>The press shift button appears to still work, but the option to start in safe mode from the programs listing of a standard install I do not think exists anymore.
Safe mode will start from a command line, (or a shortcut) and in some circumstances you may need to enter the full path name on a command or shortcut detailed instructions are at http://kb.mozillazine.org/Safe_mode
Remember (at least at this stage) do not make changes when you get the options list, just click on the continue button.
If you think that RealPlayer is causing the problem you could uninstall that for now.
Firefox recent versions are 3.6 4.0 (and 5.0 in beta). There is some debate as to whether creating new profiles or re-installing Firefox is the simplest method of troubleshooting and solving some of these problems, personally I use multiple profiles and multiple versions of Firefox, and tend to forget the required procedures are less than straightforward. For now at least try [[safe mode]] again.

TS1702 I have an iPad 1. I went to do an update on GarageBand and iBooks but it will not update. How do I return it to the original version?

Well, to paraphrase the old line, "What're you gonna believe, that email or your own lying eyes?"
The first thing I'd recommend trying is to power down your iPad (press & hold Sleep/Wake until the red OFF slider appears, then slide it to shut down), and then boot it back up and try again. You're resetting a bunch of state signals by doing that and this simple action (the first of a series recommended by Apple in your Users Guide) will quite often clear up these sorts of problems.

When are you going to make GOOGLE TOOLBAR compatible with the latest version of firefox, i will not update to version 8 until its compatible

Question
When are you going to make GOOGLE TOOLBAR compatible with the latest version of firefox, i will not update to version 8 until its compatible

It's not going to happen. Google announced withdrawal of their Google Toolbar.
Using Google Toolbar features without toolbars - MozillaZine Knowledge Base
:http://kb.mozillazine.org/Using_Google_Toolbar_features_without_toolbars
The Google Toolbar will not be updated for Firefox 5 or later Firefox versions. ([http://googletoolbarhelp.blogspot.com/2011/07/update-on-google-toolbar-for-firefox.html reference]) Google finally decided that their [http://kb.mozillazine.org/Problematic_extensions problematic extension] is beyond repair for the little benefit added for Firefox users. Google as with other browsers is eliminating or making toolbars less accessible.
Consider the features that you are using and see if you can match up features from the list created by Google and by Firefox users.

Updated to IOS6 and now my apps will not update on the Ipad2. I have to delete them and then re-install. But I have several hundred apps and this is cumbersome. Seems the new software is too buggy. I am telling people not to update software yet.

Basic troubleshooting from the Users Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.

Update for iTunes version 11.1.4.62

Once again tried to install new update for iTunes and once again the version would not install. Had an error code of MSVCR80.dll is missing. Another error that stated there was a corrupted file. Doesn't Apple test their updates? Third time this has happened. Usually I can go back to an older version. For some reason after attempting a manual installation, no older version exists and I am wary that uninstalling and reinstalling iTunes will not erase my library. Any suggestions? Thanks.

Rip it up and start again. See Troubleshooting issues with iTunes for Windows updates.

"Apple Software Update for Windows" has an invalid signature and will not install
Anyone has a solution for this??? Any help would be greatly appreciated...oh and by the way, my iPod is not connected when I am trying to update.
Thanks

Okay. Rather than using Apple Software Update, let's try updating your iTunes using an installer downloaded from the following location:
Latest iTunes Installer
Does the install using the iTunesSetup.exe from there go through any better? If not, what error message do you get from that?

Updated my desktop software to the latest version and now it will not connect to my device.

I tried a new cable. I just did a backup before I updated my desktop - version 7.1.0.41. I am running Windows 7
thanks

Teaboy's link had many links within it but not the one I usually suggest when a phone is not being recognized. Let me add my fave link:

After doing a suggested update of itunes on my pc it will not open and gives me a msg saying msvcr80.dll is not on my computer and windows error 126 has occured

After doing an update of itunes on my pc Itunes will no longer open and gives me a msg about MSVCR80.dll not on my computer and Itunes was installed incorrectly error 7 (windows error 126)

This happened to me today as well post installing the latest version of itunes. I did a search on google for the error and came across a recommendation to :
Note: Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the msvcr80.dll error.
If, and only if, you're receiving the msvcr80.dll is missing error when you open Apple iTunes, do the following: (skip this step if your msvcr80.dll error is occurring with a different program)
Uninstall from Windows the following five programs in this order: iTunes, Apple Software Update, Apple Mobile Device Support, Bonjour, and finally Apple Application Support. If you have iCloud, remove it as well.
Uninstalling these programs in Windows is done from an applet in Control Panel called Programs & Features (in Windows 8, 7, or Vista) or Add or Remove Programs (in Windows XP).
Note: Songs and playlists in iTunes will not be removed when you uninstall the iTunes program or any of the other, already-mentioned Apple programs. If you'd still like to back them up, they're usually located in the My Music folder in Windows.
Download the latest version of iTunes from Appleand note the location you're saving it to so you can find it once it's done.
Run the iTunes installation as an administrator. If you're not sure how to do that, see How Do I Open an Elevated Command Prompt? for help. That procedure shows you how to open the Command Prompt program as an administrator, but the steps are essentially the same for anything, including the iTunes installation package you just downloaded.
A general overview of removing and reinstalling iTunes can also be found here on Apple's site but the above procedure seems to work better in this particular situation.

Updated to iTunes 10 and now iPad will not sync on PC Windows XP Pro

I updated to iTunes 10 earlier today and now my iPad does not register at all in iTunes Devices pane when I try to sync it. The iPhone 4 syncs perfectly. Do I just wait for Apple to sort out the problem with iTunes 10 or what do I do please.
THANK YOU.

I had the same problem after upgrading to iTunes 10, but I'm running Windows 7. The iPad was being detected by Windows but not by iTunes. My iPod would sync with iTunes OK. Uninstalling and reinstalling iTunes alone did not fix it. I fixed it by performing the following steps:
1. Uninstalled the Apple Mobile Device USB Driver from the Universal Serial Bus controllers section in Windows Device Manager (this will only be displayed if the iPad is connected to the PC). I also selected the option to 'delete the driver software for this device' - this may be different in XP, I cannot remember.
2. Uninstalled iTunes, Apple Application Support, Apple Mobile Device Support, Apple Software Update, Bonjour and Quicktime (basically, ANYTHING Apple related) using Windows Add/Remove Programs. Your iTunes library files and media SHOULD be unaffected by uninstalling but I made a backup of mine first JUST IN CASE. They are usually located in your 'My Music\iTunes' folder.
3. Made sure 'C:\Program Files\Common Files\Apple' and 'C:\Program Files\iTunes' had been deleted by the uninstall routines. I also deleted the Apple related folders in my local profile. On XP these will be in 'C:\Documents and Settings\<your username>\Local Settings\Application Data' (you may have to enable to option to view hidden files and folders). The folders I deleted were called 'Apple' and 'Apple Computer'. Renaming them will have the same effect if you are nervous about deleting them.
4. Rebooted the PC (why not, eh?).
5. Downloaded the iTunes installation file (iTunesSetup.exe) from the Apple website. Installed it.
6. Launched iTunes, all my music, podcast subscriptions etc were preserved so I did not have to use my backup from Step 2. Connected my iPad. The device driver was installed by Windows, the iPad appeared in iTunes and I was able to sync OK.
I can't say for sure which of the steps above was key to fixing the problem, but hopefully if you do the same it will resolve your problem. Good luck!

I updated to newest version, and now it will not open. It tells me to reboot over and over.

I updated to newest version. It keeps telling me to reboot, so I have. It will not open, and I cannot even uninstall it.

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can skip the step to create a new profile, that is not necessary for this issue.
