Firefox is freezing. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox still running. I close Firefox in Task Manager & can re-start Firefox.

Firefox is freezing in the middle of a browsing session. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox to still be running. Once I close Firefox in Task Manager, I can re-start Firefox. This can happen several times in the space of a few hours? I'm running Vista Home premium with Firefox 3.6.16, and this problem has only started in the last 4 weeks. Can Anyone Help? Core 2 Duo E7300 with 4GB RAM.

Sounds like it is hanging when you exit and later try to restart Firefox.
* How to stop the running Firefox process

* You may need to try Firefox Safe Mode
** You may need to use '''Safe Mode''' to locate the problem: ***See: http://kb.mozillazine.org/Safe_Mode
***Firefox 4 users, hold the Shift key while clicking the Firefox 4 desktop icon to enter Safe Mode.
***Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox.
****In Firefox 4, Safe Mode also disables Plugins and Hardware Acceleration.
****If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode (In Firefox 4, Tools > Add-ons > Appearance). See: http://support.mozilla.com/en-US/kb/Using%20themes%20with%20Firefox#w_managing-themes-and-personas
****When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode".
****Test to see if the problem you are experiencing is corrected.
*** If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it
***#by enabling '''one at a time''' until the problem reappears.
***#You can also enable a few at a time (3-5), keeping track of what you just re-enabled to see if the problem re-occurs; this will help narrow down the possibilities if you have a large number of add-ons.
***#'''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit).
***#You can use "Disable all add-ons" on the Safe Mode start window.

App Builder won't install - have tried all recommended fixes but still fails

Hi all,
I have read the similar issues others have had installing app builder and tried the suggested fixes, but am still having trouble installing.
I have downloaded the latest version of App Builder (32.4 I believe), and am running Mac OS X 10.7.5. When I try to install i get the error "Sorry, an error has occurred. The application could not be installed because the installer file is damaged. Try obtaining a new installer from the application author."
Just out of interest, I tried installing the same file on another Mac (running OS X 10.10.2) and installed without issue. So the installer file would appear to be fine.
According to the system requirements, my 10.7.5 system should support the install, so I am not sure what else to try.
Thanks, Louise.

Ok. Please call enterprise support for assistance with this then. You can find contact information by logging into http://digitalpublishing.acrobat.com/ and looking in the bottom middle of the screen.

I have downloaded, extracted and installed Elements 12 but it will not open nor can I find the Adobe file in the file where I installed it to.. When I've tried to download and install again

I have downloaded, extracted and installed Elements 12 but it will not open nor can I find the Adobe file in the file where I installed it to.. When I've tried to download and install again it says that the "Object Already Exists." It may exists, but it is not visible in the file or in my list of programs on the Startup Menu.

You should not have to uninstall Premiere Elements 12/12.1 in order to install and run Premiere Elements 13 on the same computer unless your computer is overloaded and the computer resources are compromised. Just use one program at a time.
Can you still use 12/12.1 on this same computer that will not let you use 13?
What specific Window operating system are you using?
Let us go through the usual drill...
1. Does the problem exist with and without the antivirus and firewall(s) disabled?
2. Are you using a pen and tablet device instead of a mouse?
3. Did you install the program with antivirus and firewall(s) disabled?
4. Disable the SLCache Folder found in Windows 7, 8, or 8.1 64 bit
Local Disk C
Program Files (x86)
Common Files
Adobe
and in the Adobe Folder should be the SL Cache Folder that you delete or disable by renaming the Folder
from SLCache to SLCacheOLD.
5. Are you running the program as Administrator and is the latest version of QuickTime installed on the same
computer as Premiere Elements 13?
Let us start here and then decide what next.
Thank you.

I downloaded firefox 3.6.9 but it will not open, says it's corrupted.

Pretty simple, little icon kept popping up urging me to download the newest version of firefox, I tried twice with the same result. It seems to download just fine, but when I go to run the program it says it's corrupted and won't allow me to continue. Never had an issue upgrading before, so I really don't have any idea why it's not allowing it now.
And please dumb down any responses, I'm not technologically inclined!

Make sure your user account has full administrative permissions. Then, at this stage of the game, I would take the following steps:
- Re-create the Preferences file following these instructions:
Re-create the Photoshop Elements preferences file to eliminate problems that a damaged preferences file might cause.
Note: When you use this solution, Photoshop Elements will create a new preferences file and you will lose custom settings associated with your current preferences file. However, the file you rename in step 2 is your original preferences file. If you determine that the preferences file is not causing the problem, then you can restore your custom settings by undoing the instructions below.
To re-create the Photoshop Elements preferences file:
Quit Photoshop Elements.
Locate the Adobe Photoshop Elements preferences files. In Photoshop Elements 5.0, there are two preferences files, one for Organizer and one for Editor:
Users\[ user ]\AppData\Roaming\Adobe\Photoshop Elements\5.0\Organizer\psa.prf
Users\[ user ]\AppData\Roaming\Adobe\Photoshop Elements\5.0\Editor\Photoshop Elements 5 Prefs.psp
Rename the extension for the files (for example, to psa.old).
Start Photoshop Elements. Photoshop Elements creates a new preferences file.
I doubt that this will fix your problem, however, it is always the first thing to try. If it does not, take these steps:
- Uninstall Photoshop Elements
- Run the Windows Installer CleanUp Utility (http://support.microsoft.com/kb/290301)
- Reinstall Elements
- Reinstall the 5.0.2 patch
Good luck,
Juergen

Had elements 8 for 3 years no problem, now will not open, just disappears

I havae had elements 8 for 3 years +, but now will not open in edit - will open organise. I have tried lots of different things, but nothing works

Hi,
Please try couple of probable solutions as mentioned below:
Solution 1:
1. Close Elements.
2. Launch the Photoshop Elements Welcome Screen and hold down ctrl + alt + shift as you click Editor.
3. Continue to hold the keys until you see a message box asking if you want to delete Photoshop Elements settings file; click Yes. Elements will open with default preferences.
Solution 2: In case any network printer is attached try to launch without network or printer uninstall or make different printer as default.
Solution 3: Try launching with anti-virus off or removing PSE from conflicting list.
Solution 4:
On the drive on which you have installed PSE,on my machine it is on C:
Go to C:\Program Files\Adobe\Photoshop Elements 10\Locales\<locale>\Plug-Ins\Import-Exportand you will find twain plug-in. Remove that plug-in from that location and copy it somewhere else.
Now launch PSE and check if it works.

I had purchased Imovie today I can find the icon movie it click it but it will not open. Its shows up in docs and purchased but not apps? how do i add it to my bar and open it?!

Exactly where are you clicking, you need to be specific. For example, are you using the Dock, the Applications folder, Launchpad, etc. to attempt to start teh app? Also IOS 7.1.2 does not run on a Mac, what version of OS X is installed on your computer?

I need to make a pdf document, made in photoshop, 'page turn' and then add it to my website. I know I can do this in indesign but indesign will not open pdf files for some inexplicable reason. Any ideas how I can do it without completely starting again?

I need to make a pdf document, already made in photoshop, 'page turn' and then add it to my website as an e-brochure. I know I can do this in indesign but indesign will not open pdf files for some inexplicable reason. Any ideas how I can do it without completely starting again?

Hello waitingone,
please try this (all terms are translated from my German programs to my best knowledge):
1. Did the creator of the pdf file enable the import options?
2. See import options: choose an other visibility option for your layer.
3. Let you show the import options and click into one with a black background and try these out (often a gray is selected).
4. See trimming: try the different modes there. Often works: "Media".
5. Is the pdf file (eg from Word) correctly created?
6. Is the PDF file protected? >>> no import possible.
7. If that does not help, store the pdf file in Acrobat, repair possible errors, run the PDF Optimizer before placing in InDesign.
Good luck!

NOt an iPhoto issue - either a bad CD or a bad Superdrive on your computer - no way for us to tell try the CD in a different computer
