I am not able to register my Apple ID for iCloud and the error is "the maximum no of free accounts have been activated on this phone" can any one help me why I need to do
Sir, your Apple ID can be used as an iCloud account as well. They are both the same thing.
You can learn more from --> Set up your Apple ID for iCloud and iTunes - Apple Support -
i got this massege on my iphone the maximum number of free accounts have been activated on this iphone can any one help?
This restriction has no relation to creating free accounts, it means you may not sign in to another free account, on that iDevice because the serial number of the device (on apple's server) has their limit of free accounts associated to it. the only way around this is to use one of the three free accounts on the device which the server has associated, OR have apple reset the account/remove the restriction for that serial number...This has been posted in dozens of discussions, but they continue to ingnore the problem, what's worse is the telephone support is RUDE about it if you inquire.

Hi i am getting an error like this while installing Live Cycle Server " The file merge_modules\lc11_common_iam_zip does not exist This file is required sucessfullly run the Live Cycle Installer.Can any one help me on resolving this issue it would be of great help..thanks .
I think in your situation it would be worth trying the things listed under the event. It does have to do with FRS and it's easy to do. I've used it to fix journal errors after a server unexpectedly restarts and sysvol stops replicating. I
could see where it could fix your issue, and if it doesn't, you're out 5 minutes. :)
The listed registry key does not exist
Expand HKEY_LOCAL_MACHINE.
Click down the key path:
"System\CurrentControlSet\Services\NtFrs\Parameters"
Double click on the value name
"Enable Journal Wrap Automatic Restore"

Unknown Error containing "0xE" when restoring
To resolve this issue, follow the steps in iPhone, iPad, iPod touch: Unknown error containing '0xE' when connecting. If you have a Windows computer with an Intel® 5 series/3400 series chipset, you may need updates for your chipset drivers. See iTunes for Windows: Issues syncing iOS devices with P55 and related Intel Chipsets for more information.

Error 1604
This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode, put it into Recovery Mode.
Restore and wait for the error.
When prompted, click OK.
Close and reopen iTunes while the device remains connected.
The device should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection. -

Edited by: Konapalli.Gopi on May 20, 2010 5:42 PMSomething's wrong with your CLASSPATH.
If you're not using JDK 6, you need to include activation.jar in your CLASSPATH.
If you've got any other jar files that define the javax.mail.* or javax.activation.* classes
in your CLASSPATH (such as javaee.jar or j2ee.jar), remove them. -
I can no longer back up my iphone to my computer on selecting 'sync'. I can back up to iCloud but I get an error message telling me I cannot backup to my Mac. Can any one help? It's driving me crazy!
Hello joelfromn. charleston,
It seems you are unable to activate iMessage on a device with no carrier service. The following article provides information regarding activation issues:
If you get an error when trying to activate iMessage or FaceTime - Apple Support
Check your device settings
Make sure that you’re connected to a cellular data or Wi-Fi network. If you're using an iPhone, you'll need SMS messaging to activate your phone number with iMessage and FaceTime. Depending on your carrier, you might be charged for this SMS.
Go to Settings > General > Date & Time and make sure that your time zone is set up correctly.
Thank you for contributing to Apple Support Communities.
Cheers,

I cannot install latest itunes to my Sony notebook which is running on traditional chinese windows 7 64-bit, the error message is something like unrecognized windows package, can any one help me or has similar experience? Thanks.
iTunes 9.0.x is certainly compatible with Win7 64 bit since I use that exact setup on 3 different PCs. Two suggestions for your installation problems:
1)Download a new copy of the 64 bit installer from Apple then, instead of just running the itunes installer right click on it and try 'run as adminstrator'. In my experience that clears up a world of problems with program installation in Win7 and Vista. This is necessary even if you're already logged in as an administrator.
2) Try the previous version of iTunes (9.0.3). You can get a copy at http://www.oldapps.com/itunes.php?old_itunes=54 again right click on the file and "run as administrator"
Good luck, hope this helps.

TRYING TO DOWNLAOD DIGITAL COPY OF PROMETHEUS ONTO ITUNES. KEEP GETTING AN ERROR MESSAGE OF 5000. CAN ANY ONE HELP?
(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time? -
Can any one help? "Windows cannot repair this computer automatically."
I have a laptop satellite L455-S5000.
And when I try and trun on my computer a black screen comes on that says "windows is loading files..."
and after it loads a window pops up saying "startup repair is checking your computer for problems..."
and after that gets done it says "Windows cannot repair this computer automatically" so I click "Send information about this problem (recommended)" and then I click "finish" then it shuts down. when I try turning it back on it does the same thing over. Please can any one help me fix it? Im really clueless about computers and I have know Idea what is wrong with it, or how to even go about fixing it. thanks._Ashley_
Turn the laptop off, hold down F8, turn the laptop on and let go of F8 when you see the Advanced Boot Options.
In here, choose Repair Your Computer then press enter, follow the prompts, choose System Restore and restore your laptop to a point before the problems started.
If the laptop cant get you there, a system recovery starts the laptop from it's factory state but you loose your programs and files doing that. Holding the "0" beside "9" while you turn the laptop on boots the laptop from its recovery partition if you accept data loss. -
