Brandon Sky- sorry I am replying so late, for I have been very busy. The error message i got in Console after trying to open the file is below.
Thanks MadMacs0, for I enabled Logging to be able to see this error messsage. Do you know how to access the page that says whether you are using 32-bit or 64-bit under the Java Control Panel? everyone says that is the solution to my problem, but unfortunately it was all under "Java Preferences."
Brandon Sky- I do not know what this error message means, do u know? lol thanks :)

I had this same message appear today when i was putting new music on my ipod touch 4th gen. The only difference is that I wasnt using an external drive. I was using the one on my computer. This is the first time i have had this problem

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Mavericks Update - Error message - The product distribution file could not be verified

Help!
Trying to download mavericks (from 10.7.5) as I have just had a new hard disk isntalled and need to start from scratch.
Wanting to re download iphoto but I can't as I need a newer OS so trying to download mavericks from the app store. My internet is very slow and keeps cutting out so I have tried a few times but it's not working.
Now I'm getting an error message - 'the product distribution fil could not be verified'
If anyone can help that would be great.
Or even let me know where I can get a copy of iphoto to suit OS 10.7.5 so I don't need to download a whole new OS.

You're trying to download a 5 GB file. If your Internet connection is lousy, you won't have much success. Try another network.

I tried to download FireFox and when I hit the second run to start it an error message appeared stating the file could not be extracted why?

I did the download for FireFox and when the download was complete a screen appeared asking me to run the program. I clicked on run but at 14% it said file could not be extracted error message. I don't understand why this happened and what do I do now?
thank you
Linda

Don't try to run the program directly when downloading with IE, but save the Firefox installer to the desktop and start the installation with a double click on the desktop icon.

I recently reset my computer and copy my music from an external hard drive to my itunes library. When I click on a song to play i get an error message that says " the song could not be used because the original file could not be found". need help

I recently reset my computer and copy my music from an external hard drive to my itunes library. When I click on a song to play i get an error message that says " the song could not be used because the original file could not be found". But when I have my external hard drive plug in the song will play with no problem. What do I need to do to play my music without having the external harddrive plug in ???????? Please help

Because the location for each song in your library is on your hard drive. If the hard drive isn't there, how can iTunes play it?
You'll have to move/copy the music from your hard drive to your computer's hard drive.
Basically, EASIEST way to do all this, if you don't care about your play counts, etc...
-Delete EVERYTHING from iTunes, so that your library is now empty.
-Go to "Advanced" inside of the "Preferences" window, found in the "Edit" drop-down. You can also access Preferences by pressing Ctrl+, (Press Ctrl and the comma key)
-Change your iTunes Media Folder Location to something simple, but on your computer. I use C:/iTunes. Make sure "Keep iTunes Media Folder Organized" and "Copy files to...." are both checked. You can close Preferences now.
-Now, drag and drop your music from your hard drive into your iTunes library. iTunes will automatically add the music to your library, as you would expect, and also creates a copy of each file to place into that iTunes Media Folder you just created.
Shouldn't have any more problems...

What's the name of the file you are attempting to open? Is it "ScreenFlow_4.5.2.dmg"? If it is the correct name then the message is correct and you are attempting to open a file with DMG files extension and not one with a PDF file extension. Adobe Reader opens PDF files an not any other file type.

I recently upgraded my OS to Mountain Lion 10.8.2 and cannot open up .avi files now in Quicktime. These same files opened up with no problem prior to my upgrade. Additionally, I had upgraded to the Pro version of Quicktime recently, but it appears I've retrograded back to the basic version, unexplainably.

Hi,
I had exactly the same problem & found the answer here https://discussions.apple.com/thread/3219982?start=0&tstart=0 . Download a program called Perian, very easy to download worked a treat. I wish all fixes were this easy - Debbie

Used "Duplicate Cleaner for iPhoto" now my video files in iPhoto have an error message "A necessary data reference could not be resolved."

As the title states, I used the app "Duplicate Cleaner for iPhoto" to get rid of 6 GB of duplicate pictures. However, now when I go to view a video in iPhoto, I get the error message "A necessary data reference could not be resolved." I am able to view the video clips (with sound, etc.) in Finder. However, I want to know if there is a way to restore them in iPhoto?????
Thanks,
Leslie
I see that the suggested solution is to restore from back-up... is there anyway to do that without bringing in ALL of the duplicate photos I just deleted?

Try going back to QuickTime 7.4, we've seen the same problem occur with the 7.5 update. How did you make the .mov file that plays all of the files? For us, the problem shows up with reference movies (such as that .mov) made on a Mac, but works fine if it is created on Windows.

hope its a mandatory feature as laptop and mobile interface are simple task nowadays in mobile...
pls reply me..its very urgent...thanku..

You could try Videora (http://www.videora.com/) - the downside here is that they have specific versions for specific phones, and sometimes it will makea file that plays perfectly in the desired phone but can't be shared to other models. The don't show a version for the N79, but try the N96 one because the N96 is the most similar OS to yours that they offer.

received error message - the procedure entry point_objc_init_image could not be located in the dynamic link library objc.dll. unable to launch iCloud. Any suggections?

I had roughly the same error. I fixed it by running the iCloud control panel update from apple software update. The problem cropped up after I ran the most recent iTunes update, I've personally been having issues with iTunes updates being finicky since upgrading to Windows 8.1, I've had to download installers rather than running the update directly through Software Update, so it's possible Apple is not fully addressing compatibility issues for newer versions of Windows. Ultimately it seems to be a missing file issue, so any update, installer, or install verification/repair that directly addresses the iCloud files should see and replace the missing file.
Also it looks like Apple is either unaware of this problem or not addressing it at all, there are about a dozen support requests from within the last month all asking this same question regarding iCloud, just with different specific files unable to be found. None of them have answers.
Hopefully this works for you

With those symptoms, I'd try the following document:

(If there's a SpeedBit LSP showing up in Autoruns, it's usually best to just uninstall your SpeedBit Video Accelerator.)

My iTunes parent control keeps giving me the same error message. "Parent control preferences could not be unlocked. You may need to reinstall iTunes. "I have uninstalled ant reinstalled iTunes that 4 time now and I still can't get on. Can anyone help?

My iTunes parent control keeps giving me the same error message. “Parent control preferences could not be unlocked. You may need to reinstall iTunes. “I have uninstalled ant reinstalled iTunes that 4 time now and I still can’t get on. Can anyone help?

Experimental advice ... but, plausibly, the preference files containing the parental control setting may be damaged. If so, removing the iTunes preference files may help.
For the basic technique, see the "Remove iTunes preference files" section from the "User-specific troubleshooting" section of the following document:
iTunes for Windows Vista or Windows 7: Troubleshooting unexpected quits, freezes, or launch issues
To see those folders, you'll need to first set your PC to view hidden files and folders
In your Start menu, open Computer.
In your Organise menu, select Folder Options.
In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
Click OK.
Prior to doing the preference file rebuilds: Best to make a note of any custom preferences you have set up for your iTunes. (Rebuilding pref files returns preferences to their defaults ... so you'll likely have to set some of those custom preferences up again from scratch.) Also make a note of any third-party plugins/add-ons you have installed. You may have to reinstall those after the rebuilds.
Things to watch out for during the rebuilds
Rebuilding the preference files in the \Local\ location causes the iTunes license agreement to run. So you'll need to agree to that again.
Rebuilding the preference files in the \Roaming\ location causes the iTunes Setup Assistant to run. When prompted to do so, do not add files to your iTunes library. (Otherwise you'll end up with a library full of duplicates.)

Time Machine Error Message: "The backup disk image could not be mounted"

I just installed Time Capsule and the initial back up was going smoothly. Now
all I get is a and the Error message "The backup disk image could not be mounted". Can anyone help me troubleshoot this problem? Thanks.

This works, if there is no corruption in the sparse image. But after weeks of backups, my sparse image on a USB disk attached to an Airport Extreme was corrupted.
I am right now repairing it by connecting the USB disk directly and using disk utility. It recovered the file system and is not rebuilding the B-Tree. I hope that works, otherwise it will have to be disk warrior...
On Time Capsule, I have heard folks having success with attaching the image, and then repairing it:
hdiutil attach -nomount -readwrite /path/to/sparse/image
Your mileage may vary, but you do not have a lot to lose in this circumstance...
This functionality should really be in the Airport or Time Capsule, or at least Disk Utility or Airport Utility.

Error Message: This type of file is not supported, or the required codec is not installed?

I am trying to get media from my computer, and I only receive this error message :
This type of file is not supported, or the required codec is not installed?
What should I do? I have a window 8 laptop. My video files are from my itouch/ipod. I am using Premiere Elements 7.
I have used this software with success before. HELP would greatly be appreciated!

darlingdarleen
Did both laptop 1 and 2 have QuickTime (latest version or any version) installed on the computers with Premiere Elements 7 when you got this "this type of file......" message?
If you go to the opened Premiere Elements 7 projects involved and look at Share/Personal Computer/QuickTime, do you find that QuickTime Presets are shown and that you find export settings choices under the Advanced Button/Video Tab and Audio Tab?
Look at the file name of the video. Do you see any irregularies in the name of the file, dots and such?
If you record new iPod footage, open a new Premiere Elements project, and import that iPod footage, do you still get the error message? Putting aside, iTouch, what model iPod are these videos coming from?
Thanks.
