Just attempted to run the update and still rec'd the same message. I also see that there are many others who are havig the exact same problem. How can I get Apple support to look at it?

How do I update from MAC OS X 10.6.8 to a later version? The software I'm trying to run indicated I needed MAC OS X 10.7 or later.

How do I update from MAC OS X 10.6.8 to a later version? The software I'm trying to run indicated I needed MAC OS X 10.7 or later.

Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

I've had all kinds of trouble keeping my iTunes software current over the past year, but have found the easiest way to remedy the issue is to simply download the latest version of iTunes as though I am a first-time user and then just install it into the directory my current version of iTunes is using. Doing this has allowed me to update my software without losing any of my media/data. Hope this helps! Best of luck!!!

Firstly, are you installing iTunes for the first time or are you updating your current version of iTunes?
If you're installing iTunes for the first time have you tried redownloading the installer package? Perhaps the file you downloaded originally is corrupted...
http://www.apple.com/itunes/
If you've tried that, then try installing iTunes as your computer's administrator. To do this right-click the install package and choose "Run as administrator".
If you're updating iTunes to the most recent version try repairing the Apple Software Update program on your computer. It's under the add/remove programs.
1. Open the control panel
2. Open Add/Remove programs (called "Programs and Features" in Windows 7)
3. Navigate to "Apple Software Update" in the list and click on it
4. Click on "Change" then select "Repair" (or just select the repair option in Windows 7)
Once you repair this, try running iTunes and the update again.
Fingers crossed!

I changed my wireless broadband to a landline-base DSL wifi and it works like a charm. Sun was the culprit even you fiddle with its router and disable firewall, it won't work.
try changing yours too and let me know how it goes.

Thanks for your reply. My Mac is running 10.5.8: it's 4 years old. When I try to update the OS software, I'm told there are none available.
Be careful - there's a difference between update and upgrade. Your machine is saying there are no updates available, meaning no later versions of OS X 10.5 (Leopard). However, you can very likely upgrade - at least to OS X 10.6 (Snow Leopard), and possibly then to OS X 10.8 (Mountain Lion).
Updates are free, but upgrades cost a bit. That's the dirference.

HT5621 Hi I'm using my wife's email for my apple Id but now she has got an iPhone we r both using the same one ive tried gettin my own using my own email but it keeps telling me my email is already in use how can that be????

Are you trying to set up your own iDevice and that is why you want your own Apple ID?
Do you realize that any content that you have already purchased using her ID will still have to be used if you want to update apps or download purchases again for free? ITunes and App Store content is tied to the ID used to make the purchase. Furthermore, if you use her ID to download a purchased app for free on your own device, you can lock yourself out of your ID for 90 days.
Back to the question at hand .... Did she use your email address as the rescue email address for her Apple ID?

Trying to install Adobe acrobat from disk to computer error keeps saying can't complete instillation

Trying to install this piece of crap program from adobe "acrobat" that they offer no support for. It is 11 Standard and I have windows 8 and keeps telling me in error can't complete instillation. No other details. Any ideas? Can't believe they sell this for the price of a tv and offer only us to help each other.

Hi Jennifer ,
Sorry to hear that you are experiencing with Acrobat .
Could you please tell is there any error number or exit code mentioned along with the error message ?
It might be possible due to insufficient space on your machine ,it is not letting you install Acrobat .
You could try deleting the temporary files from your system once and check if that helps .And make sure all the third party software are disabled while the installation is in progress .
I would also suggest you to refer the following document to seek help .Have a look at this document and see if that fixes the issue .

Can't re-install previous purchases from Mac AppStore

I previously deleted the Victoria 2 games that I had bought and installed from the Mac AppStore. I've done this so many times with Steam because I don't like games/apps that I don't use taking up space. Then I go back and reinstall later if I want to. But with the AppStore, under the place where it says "purchases", when you click "Install" it makes an attempt for like a second and then just reverts to the "install" button. I can't install them, and it's really very infuriating.
Please help!

NEVER MIND; Resolved. Appearantly when you go directly to the particular app in the store and click "install" there it works, as opposed to tyring to reinstall it from "purchases"....very strange..
