I can't open my AVI files and see video, I only hear the audio with a black screen. My format for my dash cam is H.264. When I try and open my files the messeage I get is
The document “DR153659.AVI” could not be opened. A required codec isn't available.

It's most likely in VLC or Perian, but may not exist for Mac OS X.

When I download firefox, using recommended setting, or my own, all the sub files/folders like plugins, modules, updater end up on the desktop as well as in the file location. And when I try to put them into the file location, they don't. And when I delete them, FireFox won't open. I tried deleting FireFox and reinstalling it multiple times, and a message pops up sometimes that says FireFox may not have installed correctly, so I follow the steps, but all the extra icons on my desktop don't go away. This has happened every time I have downloaded FireFox. The browser itself works, but I need to know how to get rid of these icons, but still be able to use FireFox. This is on a new computer, with Windows 7.

The folks here would need far more information from you before they provide help.
You know the drill: Exact OS...PS version...etc. The more you provide, the better.
What is the exact message that is displayed?
What have you tried so far?
Do the files display on your browser? In Bridge?
What are you doing when it happens?
Are the files still on your cameras card? If so and,you copy one to your desktop and save it without changes, does it reload properly?
Don't worry about providing too much information. Every little bit helps.

I've signed up for a subscription to acrobat pro and successfully download 2 days ago. Now when I try to open pdf it asks if I want to sign up again and will not allow me to open the document.

Hi Mbs@adobe,
It sounds to me like you're trying to open a PDF via one of the Acrobat online services, not via Acrobat. Did you install the file that you downloaded after you signed up? Once you do, Acrobat will be installed on your computer, and you can run it locally (you don't access an Acrobat Pro subscription via the web--it works just like a version of Acrobat that you might purchase from the Adobe Store, or a large retailer).
Then, you'll open the Acrobat application from your desktop and choose File > Open to open your PDF file.
Please let us know how it goes.
Best,
Sara

Have you upgraded to iPhoto 9.6 for compatibility with Yosemite? If not, try that first.
It looks like iPhoto has lost the connection between the thumbnails and the original image files.
This can be caused by a corrupted iPhoto library, or the originals have been deleted or moved.
Try first to rebuild your iPhoto Library:
If you do not have a current backup of the iPhoto library, make a copy of the library, but do not overwrite any previous backup.
Launch iPhoto with the ⌥⌘-key combination (option-command) held down.
Select "rebuild" from the first aid panel. This may take a while for a large library.
Can you now see your photos again?
If not, rebuild the library with iPhoto Library manager as described by Old Toad: Re: iphoto crashed

Hi, Hugo,
In similar cases it helped to remove the GarageBand "Preferences" file from the User Library.
Open the folder
your home folder > Library > Preferences
and move the file "com.apple.garageband.plist" to the Desktop.
Then try again to launch GarageBand.

Have CS 5 Installed on my iMac and works ok. But installed on my new MacBook Pro it won't open NEF files from my Nikon D810. Displays NEF icons, but when I try and open them the response is: Make sure latest RAW updates are installed. If problem persists

Have CS 5 Installed on my iMac and works ok. But installed on my new MacBook Pro it won't open NEF files from my Nikon D810. Displays NEF icons, but when I try and open them the response is: Make sure latest RAW updates are installed. If problem persists follow link: http://www.adobe.com/go/kb407111. Have installed Bridge 5.0.2.4; Raw Ref Version 7.0.0.308; DNG converter_8_7_1.dmg; Bridge 5.0.2 Update 2. Also same problem with Lightroom which I don't normally use. Lightroom_3_LS11_mac_3_6.dmg installed.

In the link you posted it states that the Nikon 810 requires ACR 8.6 or newer.
Version of ACR are specific to versions of Photoshop. You cannot use 8.6 nor even 7.0.in CS5.
I believe that ACR 6.7 is the latest that will work with CS5, so make sure you have this installed and get rid of ACR 7.
Having 2 versions of ACR will cause problems.
You have already downloaded DNG Converter 8.7.1.
Have you double clicked the DMG file to allow you to install DNG Converter on your computer?
Be aware that DNG converter is a stand-along application and not a plug-in.
You need to open DNG converter at select the FOLDER that contain your .NEF files.
Don't open the folder and try to select individual files, it doesn't work that way.
After converting your D810 files to DNGs you can then open the DNGs in CS5
The problem is your camera didn't exist when CS5 & its version of ACR was developed.
i don't use Lightroom, but the list mentions Lightroom 5.6 as needed to open D819 so your 3.6 version of LR won't cut it.

I recently downloaded a series of instructional videos. They are in mp4 format and rather large (~500MB on average). When I try and open them with Quicktime (default) they will not play. Are there file size restrictions? Any suggestions would be great

Try VLC Media Player. It has a reputation for playing just about anything you throw at it.

Hi there, my iMac has automatically been deleting files from my thumb drive when I try to open them. The lost files aren'tin the trash or anywhere else I can think of. Any ideas?

If one drive works and the other doesn't that points the finger at the errant drive. They are cheap, replace it. To check formatting right click it in Finder and choose Get Info and look for Format type. Finally do you eject it when removing it or do you just pull it out of the USB connection?

I have some apps on my ipad and I want to install more ,but it doesn't show the apps on the home and when I try to open them from the AppStore it doesn't work , what should I do?

Are you not seeing the icon of the app you just downloaded (it happens sometimes, and the quick fix is to reset your iPad)? Or are you running out of space on your iPad?

The books are all in my library but when I try to open them the app glitches and closes out.

I have an iPod 4g and I had deleted the ibooks app but downloaded it again. The books are all in my library but when I try to open them the app glitches and closes out. Before the app update (ios 7) and after the update it hadn't worked (for the past week).

I think I have found an answer on another page! If anyone else wants to know just do this:
Hold down the home and sleep button (if the turn off button comes up just ignore it) and when you see the apple logo release the buttons and let it wake up!
It worked for me and seem to work for a lot of people. Hope this helps!!

How do I copy my old xl files from my XP machine to operate on xl for Mac on my new iMac. When I copy them onto a stick and transfer them it automatically makes them xls files which are then corrupted when I try to open them in xl for mac

How do I copy my old xl files from my XP machine to operate on xl for Mac on my new iMac. When I copy them onto a stick and transfer them it automatically makes them xls files which are then corrupted when I try to open them in xl for mac

Sorry, yes this is Microsoft Excel. The Microsoft XP has Excel files denoted as xl, the later versions of Microsoft Excel are denoted as xls files. The later verions of Microsoft Excel open the xl files OK, does Excel for Mac not able to do this?

My computer has some serious problems, my iphoto only shows thumb size pics when I try to open them, i tried to rebuild my files from folders that had the pics in them. originally all the photos has a large delta with a question mark. also I can't back up

my computer has some serious problems, my iphoto only shows only shows thumb size pics when I try to open them, i tried to rebuild my files from folders that had the pics in them. originally all the photos had a large delta with a question mark. also I can't back up the library file because its not there. I went to time machune and tried to find the file but I can't find it or I am looking in the wrong place. I also lost my Idvd file, only have broken chain showing.

Details please
What version of iPhoto and of the OS?
i tried to rebuild my files from folders that had the pics in them.
Exactly what did you do and how did you do it? this ay be the cause of your issue but without details we can n=ony guess
my iphoto only shows only shows thumb size pics when I try to open them,
where do you see htis? In the iPhoto window? what does "try to pen them" exactly mean?
originally all the photos had a large delta with a question mark.
Ok - this usually has a simple solution - do you still have a copy of the library that has this problem?
also I can't back up the library file because its not there.
This makes no sense at all - all of your previous statements indicate that you do have an iPhoto library but have some problems with it
By default your iPHoto library is located in your Pictures folder and is named iPhtoo library - if tha tis not the case the you have moved or renamed it and only you know what you did until you tell us the details
I went to time machune and tried to find the file but I can't find it or I am looking in the wrong place.
Again unless you actually share what and how you are doing thing but continue to simply state abstract problems it is no possible to assist you - details on using Time Machine are here -- http://support.apple.com/kb/HT1427?viewlocale=en_US&locale=en_US -- and -- http://pondini.org/TM/FAQ.html ---
I also lost my Idvd file, only have broken chain showing.
This would be better addressed in the iDVD forum - but again unlesss yu share detailed information no one can assist

It means that iPhoto can't find the file.
- What version of iPhoto.
- What version of the Operating System.
- History: Is this going on long? Has anything been installed or deleted? - Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
