When updating iTunes I get a message saying invalid signature and it won't update, is there a fix for this?

When updating iTunes on my PC I get a message saying "invalid signature" and it won't update. Is there a fix for this that I can do myself or do I need to take it in to a computer guy?

When I make an outgoing call the recipient cannot hear as though the volume were turned down Lowe. However when I use my speaker phone function the recipient can hear at normal volume. Is there a fix for this issue? Thanks Teresa

Hey Tlabounty,
Thanks for the question. I understand you are experiencing issues with the microphone on your iPhone 5. To troubleshoot this issue, you may find the information in this article helpful:
iPhone: Microphone issues
http://support.apple.com/kb/ts5183
Note that speakerphone and regular calls utilize seperate microphones on the device. It sounds like you have isolated the issue. Furthermore, if you determine that the issue is hardware related, the following resource may help you get started with the service process:

When openning itunes, I get a message saying I need to reinstall itunes if I want to burn cds. I already tried removing and installing lates itunes version but does not help. Does anybody know anything about fixing this issue?

I cannot burn cds from itunes. Every time I open itunes i get a message indicating i need to reinstall itunes. I have already done so but it's not working. I still cant burn cds. Does anybody know how i can fix this? My windows media player burns cds just fine.

I am having this same issue with Windows XP. The exact message that I get everytime that I open iTunes is :
The registry settings used by the iTunes drivers forimporting and burning CDs and DVDs are missing. This can happen as a result of installing other CD burning software. Please reinstall iTunes. I have deleted and reinstalled iTunes three times. I also have a problem with iTunes randomly opening itself.

I accidentally deleted QuickTime from my computer. Then I did a system restore and retrieved it. Now Itunes can't find QuickTime and will not open. Is there a fix for this without my Ipod?

I accidently deleted QuickTime from my computer. Then I did a system restore and retrieved the program. Now Itunes can't find QuickTime and will not open.Is there a eazy fix for this without using my Ipod? Ihave 6K songs in Itunes that I can't get to.
Thank You

Hmmm. There's a couple of things that might be going on with that one.
Let's try an uninstall and reinstall of QuickTime first.
If you're using XP, head into your Add or Remove Programs control panel. Select "QuickTime", click "Change" and then click "Remove".
If you're using & or Vista, head into your Uninstall a program control panel, select QuickTime, and then click "Uninstall".
You can get QuickTime back either via Apple Software Update (in your Start menu go "All Programs > Apple Software Update" ... QuickTime should appear in the "New Programs" section), or by downloading a QuickTimeInstaller.exe from the following location:

Does your iTunes launch properly now?

I have 15,686 photos on iPhoto 11 and am now, when uploading latest photos, getting a message saying that my startup disk is full. Is there any way of increasing the capacity of the start up disk?

I have 15,686 photos on iPhoto 11. As I've been uploading the latest photos in the last two days I've been getting a message stating that my start-up disk is nearly full. I had no idea there was a limit. Is there any way of increasing its capacity? I have been shooting in Raw of late and I know it takes up a lot of space but I have heard of other people who have over 20,000 photos on their computers, so what is going on here??

Two possibiilities here:
1. Your start up disk is nearly full
Or
2. You have minor damage to the iPhoto Library and it's giving you a bogus message.
But here's the thing: A full start up disk is a very serious issue and needs to be dealt with fast.
So, how big is your Hard Disk? How much free space on it?

Each morning I get a notice to download a Firefox security update. When I click install, I get a message saying Installing Firefox and Connecting to the update server. It never connects; the progress bar just spins all day.

Since shortly after installing Firefo 5 I get this message every time I start Firefox. A dialog box comes up that says Installing Firefox, followed by a spinning progress bar, followed by "connecting to the update server." It never progresses past this point and will stay this way indefinitely until I close the Window.
Also since installing Firefox 5, the program crashes at least once or twice a day and I have to quit and restart. Don't know if there's any relationship between the two issues.

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Trash the current Firefox application to do a clean (re-)install
* Install the new version that you have downloaded
Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data.

Once I accept a calendar invite on my iPhone, I cannot delete or otherwise modify it. Even when it is updated or deleted by the invitor, it does not change on my iPhone. Is there a fix for this?

Once I accept a calendar invite on my iPhone, I cannot delete or otherwise modify it. Even when it is updated or deleted by the invitor, it does not change on my iPhone.

My husband and I both have iphone 4's and we both have this same problem. I have an open ticket with apple, but so far they haven't been able to figure this out. First, they told me the problem was the mail server I was using. So, I tried sending/receiving invites from gmail and yahoo which they told me should work. Neither did. It doesn't matter whether the original invite was created in iCal or in Outlook or Google, once I open the invite in my mail and hit "add to calendar" the event is locked into my calendar. If the originator sends an update or cancels the meeting, I will receive an email with the new info, but the event doesn't change in my iphone calendar. This is completely lame. Why bother putting a calendar app on the phone if it can't handle basic functions?
Did you ever get a response from anyone or figure out a workaround? I'll post if I hear back from Apple with a fix.

Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
To install the utility, doubleclick the msicuu2.exe file you downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.
