I run Windows 7 and the newest version (10.6) of iTunes will not install. The installer won't even begin, and when I run the Apple Software update, it tells me that iCloud and iTunes have invalid signature.

When I run the Apple Software update, it tells me that iCloud and iTunes have invalid signature and will not be downloaded. When I DL iTunes64setup.exe, the program will not start (there's a bar that flashes but nothing actually begins). I've done everything short of reinstalling Windows to fix this (system resore, unistalling all Apple products, taking down firewall, running Windows FixIt - which either won't find the problem or gives me an error saying that the troubleshooter cannot be downloaded at this time, going into the security features to allow programs without valid signatures, trying to install earlier versions of iTunes). It all started when I downloaded the Decemberists new album on my iPhone, and it wasn't downloading it properly so I connected it to my Dell, but some songs still wouldn't DL - also, the newest OS for my iPhone still won't install via WiFi - and so I uninstalled iTunes first, but nothing is helping. And I don't have any security issues (Norton has checked). Any ideas? I'm at my wit's end after 3 days of this. Thank you.

Ok, so after like 4 days of going through all these different issues, I figured out that several programs weren't downloading, and it was an issue with my wireless connectivity messing up the digital signatures, so if you plug in your comp to the modem and delete your temp files, it should start to work!

I downloaded the newest version of firefox but it will not install, it is giving me a message saying the directory name is invalid. Why and what can I do to fix.

The above message pops up when I try to install the new version of firefox. It will not let me install the new version. I do not know how to fix it. Please advise.

Try a custom install.

I've got the same problem and can't find a fix...

I have a PC and my itunes will not work. It won't even try to load

My library works but when I click on itunes it will not even load. I even wait for it to pop up but it won't.

Dude you have a jailbroken phone as stated in your first post, no need to do a second post.
As per the forum term of service you can't get help here. Use google.
that's the downfall of jailbreaking your phone.

The newest version... 4 will not completely load my home page and goes "milky"..and will not resolve.

Firefox will access..though the screen goes "Milky" at any attempt to browse. Another browser is working..so this is NOT my computer's problem.

In solving at least part of my own problem I've just discovered that in my just upgraded version 4, at least with Yahoo mail, I find that if I initiate printing an email from the orange upper left "Firefox" drop-down, only page 1 prints. HOWEVER, if I click on the "print" button immediately above the message, the entire message prints properly. Some web sites still only print page 1 because there is no other way than the drop down to access a print dialog box.

Since I have updated to the newest version 5 My Yahoo toolbar will not work or allow the settings to be loaded to toolbar. I have reinstalled the toolbar to the Version 2 didn't help

I have tried updating plugins and have tried updating the Yahoo Toolbar as a plugin and that has not fixed it yet. I get an error code saying that it could not be downloaded or updated because Firefox cannot find the proper file or something to that. I really need that toolbar because all of my bookmarks are there. I have tried to download the Firefox Bookmarks plugin and I get the same error message.

I have the exact same issue. I havent found our what is causing it either. Multaple re-install attempts with no success. I have to use Windows Media Center to burn audio discs. Any other advice?

Itunes will not install/upgrade?

itunes will not install, keeps trying to save to g:/ drive when it does not exist, will not let me change drive?

+"E:\iTunes\iTunes.Resources\sv.lproj\Ringtone.nib". The file is there and if you clik on it it says it is bad. It is marked read only and will not let me change this or delete it or anything. After you clik cancel install another message box comes up and says:"The installer has encounted an unexpected error installing this package. This may indicate a problem with this package. The error code is 2330".+
Yeah, the 2330 is usually associated with a bad file or folder interfering with an install.
Try running a chkdsk over your C drive:
How to perform disk error checking in Windows XP
Des the chkdsk find/repair any damage? If so, can you now move or delete that file? If so, will an itunes install go through properly now?

TS1702 itunes will not install

Itunes will not install to my computer

Can you describe what happens when you tryin to install it? Does the download start and then stall? Are you getting the dreaded "waiting" icon?
Did you try resetting/rebooting your iPad after you restored? Sometimes that helps.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

I am in the same boat. I tried repeatedly to contact iTunes support, but was told each time that I had contacted the wrong deaprtment and they could not help me. There must be a way to still be able to use the iTunes store without paying for a system update. If not, I hope they will reimburse me the money I have in my acount.

After loading Maverick iTunes will not launch. I get an error code: -45054. I am the administrator and have no groups or guests. Sharing options don't fix this. Also Fetch will not launch, I get error code: SSL error 9807. These worked perfectly before installing Maverick. Also everything that loads, all programs, take twice as long to load. I have MacKeeper and have cleaned and discarded all the garbage.

Remove "MacKeeper" as follows. First, back up all data.
"MacKeeper" is a scam with only one useful feature: it deletes itself.
Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions.
If you have incompletely removed MacKeeper—for example, by dragging the application to the Trash and emptying—then you'll have to reinstall it and start over.
IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.
In the Finder, select
Go ▹ Applications
from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. You'll be prompted for your login password. Click the Uninstall MacKeeper button in the dialog that appears. All the functional components of the software will be deleted. Reboot.
☞ Quit MacKeeper before dragging it to the Trash.
☞ Don't empty the Trash. Let MacKeeper delete itself.
☞ Don't try to drag the MacKeeper Dock icon to the Trash.

Nonsense, and very misleading advice. I've updated iPhone 3G, 3Gs,and 4 through itunes many times, never had a problem once, not with one single update in nearly 5 years of iPhones. Of course, I've never jailbroken my phones either. Hack your phone and have update problems? I've got news for you, the problems are not a result of iTunes or Apple's updates.

I just purchased an IPAD2 and am trying to install ITunes. Itunes will not install. My error message is 'Apple Mobile Device' failed to start. Verify you have privileges to start system services. This is an XP service Pack 3 and I am the only user.

I would like to be able to use my IPAD. Itunes will not install. It tells me it cannot start Apple Mobile Device Services I am using XP service Pack 3. I am the administrator. The message also says to verify that I have sufficient privileges to start system services.

That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?
