I am running OS X 10.7.3 and now Outlook 2010 will not open. It flashes quickly and the disappears.

I am running OSX version 10.7.3 and Outlook 2010on a Mac Book Pro. When I attempt to open Outlook, it bounces and then flashes quickly on the screen but then quickly disappears.

Make sure Microsoft Office is up to date. You can do this buy going to Help menu and "Check for updates". If that doesn't resolve it I would recommend removing it and reinstalling it.

Firefox used to run but now will not open. I have tried the reset and allowing windows firewall. Any suggestions?

Window 8 on new computer. Set up by outside computer person. Firefox has been running and working fine for at least 6 months. Starting yesterday Firefox will not open. I tried the uninstall reinstall, simple firefox restart, allowing windows firewall for Mozilla. I am not a real savvy computer person. Any easy fix?

Try windows safe mode does it work there?

I cannot get Audition 3 to run on my PC, i have downloaded it but it will not open when i go to open it

i have downloaded Audition 3 on my PC but when i go to run it, it is sticking on the 'initializing required components', can anyone help with this issue?

You might get better advice on the audition forum Audition CS5.5, CS6 & CC
But for starters, try deleting the preferences 3.0 folder at C;\Users\username\AppData\Roaming\Adobe\Audition\
Then start the app as administrator by right clicking the Au 3 exe file and choose Run as Administrator

Firefox will not open and states that its already running. But is not?

After several opening and closing of Firefox several time it will not open when I click on the desk top icon. A screen will come up that Firefox is already running and that I will have to close it before I can start Firefox. To correct this I have to restart the computer. It will then work ok for a few time but will then not start again.

My computer says firefix is running....I can not find it and when I click on the icon it will not open. What can I do?

I can not get firefox to open when I click the icon. A box appears and tells me firefix is running but I can not find it anywhere. I have tried to delete it and everything else I can think of and it will not open. Please tell me what I can do.
Thank you Lisa Brown

I used to have this problem on my old XP computer, too. The easiest way to fix it is to restart your computer. Use Shutdown and restart. This will stop the firefox process that is hanging and won't show up on your screen.
If you are somewhat computer literate, you can look at all your running processes by pressing Ctrl Shift Esc all at once using the three finger salute. Look at the list of processes to find firefox, highlight it, and select end process. Then go back and click on your shortcut to your firefox to regain control and display it on your screen.
Be sure to upgrade to the latest version of firefox, Version 5. It works much better than previous versions.

I am running windows 7. We updated firefox and it would no longer open. I uninstalled it and reinstalled from firefox website. I click on the firefox icon and it will not open. Help please

It installs and I attempted to launch the browser and it never starts. I tried to uninstall, but it says firefox is running. I restart my computer and uninstall and try again. It still will not open after install is complete. Why won't it ever open up? Help please!

Right-click on your Windows Taskbar and select Start Task Manager. Look in Task Manager for processes running that are Firefox-related, such as Firefox.exe or plugin-container.exe. If you see either of those, right-click each of them and select "End process". Then try again to start Firefox in [[Safe Mode]]. 
*If Firefox will start in Safe Mode, select the option you are presented with to disable your add-ons and plug-ins and restart Firefox normally. You likely have a plug-in, add-on, or a combination of two or more that is causing the problem. Because Firefox allows users to customize endlessly, sometimes there can be conflicts between customized items. From the Firefox menu bar, go to Tools -> Add-ons then re-enable them one by one, restarting Firefox after each and testing after each one to see which one or combination of two or more is causing the problem. 
*If Firefox will not start in Safe Mode, make sure you again check Task Manager and end any running instances, then uninstall Firefox and download a fresh copy from mozilla.org/firefox using another browser temporarily. Re-install Firefox (see: [[Installing Firefox on Windows]] for more help ) and try running Firefox again.
Please report back your progress.

After the last upgrade, my firefox will not open. Task manager says it is running, but I get nothing.

I finally allowed the last update to run... upon completion, my browser window would not open. I rebooted, got the window to open but had no function on the navigation bar. The only way I could navigate the web was to go to my home page, google, search for the web page and click on the results. Refresh also would not work. I did another reboot and now I'm back to no visual evidence of the browser window being open. It seems like every update for the past few months crashes my ability to utilize my add-ons and my ability to see video is almost always compromised. I try to ignore updates but the reminder keeps popping up so frequently it becomes a nusiance and I cave to the pressure!

Firefox will not open unless I run it in compatibility mode (Windows XP SP 3), run it as an administrator, or launch it immediately after a reinstall (the reinstall thing only works once.) How do I fix this?

This morning, Firefox crashed. After this, when I click the Firefox icon, the hourglass appears and then nothing happens. Firefox does briefly appear in the task manager when I do this.
I tried rebooting. I tried reinstalling multiple times. (Firefox will run when I select "Launch Firefox" from the installer. Then the problem occurs again.) I tried safe mode. I have found that Firefox will work if I select Windows XP compatibility mode from the icon properties menu or if I run the program as an administrator. When I do this, Windows asks me if I want a program to be able to make changes to my computer.
I have noticed that a Windows Error Report is being generated each time Firefox will not open.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Firefox 4.0 will not open at all. It shows that the process is running in the task manager but will not open the window even after closing the prcess and restarting.

I have had firefox since an earlier 2. version and have been able to upgrade as normal. After the installation is done it will not open at all. I have restarted and even uninstalled all previous version .exe and still nothing. I am using windows 7 OS. I am still running 3.6.8 and would love to see the new one running on my laptop.

hello, this crash is caused by Websense Endpoint security software that is running on the system. please try to install all the updates for this program that are available...

My imac was running snow leopard and was upgraded to Mt. Lion. My Microsoft Office for Mac now will not open. SO since my Office was 2004, I just purchased Office for Mac 2011. Do I delete the icons before loading Office 2011 OR after I load 2011?

Upgraded my Imac to Mt. Lion and now the Microsoft Office icons will not open WORD, EXCEL, POWERPOINT, or ENTOURAGE. I just pruchased on Ebay
OFFICE 2011 since my old version was 2004. DO I REMOVE THE OLD ICONS BEFORE LOADING OFFICE 2011 RO AFTER I LOAD IT???
THANKS, DR PEPPERMINT

Office 2011 will install in a separate folder. But do not install Office 2011 until you remove Office 2004. It comes with its own uninstalled located in the MS Office folder. Only use the uninstaller to get rid of it. Then install Office 2011.
Office 2004 and Other Applications Don't Work in Lion/Mountain Lion
If you have Office 2004 which is a PPC-only suite, it will not work in Lion/Mountain Lion. You need to upgrade to Office 2011 - Mactopia - or you can try the freeware suite, Libre Office, that is functionally similar to Office 2007 for Windows except it works on Lion/Mountain Lion.
You may want to consider as well:
These two suites are similar to Libre Office but not as current or as well-supported:
NeoOffice
Open Office
And, then there is Apple's iWork suite:
Pages - word processing and layout
Keynote - presentation
Numbers - spreadsheet
Each can open and save Office compatible files. They may be purchased separately via the Mac App Store for $19.99 each.
As for other software, any PPC-based software will not run in Lion or Mountain Lion because Rosetta is no longer part of OS X. You will need to upgrade to Intel versions of the software.
(Access to the Mac App Store requires Snow Leopard 10.6.6 or higher and an Apple ID.)

I have a Mac running OS 10.5.8. I downloaded Firefox 4 and not the program will not open at all. I am also unable to download the previous version that was running fine. I'm using Safari to contact you.

I have a Mac G5 running OS 10.5.8. I downloaded Firefox 4 and now the program will not open at all. I get an error message that reads --
"You cannot open the application 'Firefox" because it is not supported on this architecture."
I am also unable to find a link to download the previous version (3.6) that was running fine. (I'm using Safari to contact you.)

Same proble here, although the Firefox system requirements says it is OK to have PowerPC G3 G4 or G5 ( I have G5 2GHZ)
My solution; very simply use timemachine to restore the previous Frefox 3.x
worked great in 3 mns

Firefox will not open. Process runs, but browser window will not open.

I am unable to get the Firefox browser window to launch. The application will attempt to open, but the browser window will not appear. Task manager indicates that the process is running, it just will not launch the window. No amount of restarts or reboots will make a difference. The strange thing about this is that Firefox has never run. This is a new computer and this issue has been a problem since it was first plugged in.
Troubleshooting steps attempted thus far:
1) Attempted to open in safe mode - will not open
2) Attempted to run in administrator mode- will not open
3) Completely uninstalled application, including profile info and reinstalled
4) Uninstalled known conflicts - Skype 4 (do not have Norton)
5) Even though issues since new, I ran a virus scan just in case-nothing
6) Uninstalled Chrome which I installed after originally being unsuccesful at getting FF to install (I uninstalled it before I began all of these troubleshooting steps as I have heard of conflicts)
I am now at a loss and willing to try any other steps that you guys can suggest.
Computer is running Windows 7 pro 64 bit. Running McAffee virus software. There are three identical computers in my office, purchased at exactly the same time with the same configuration. Mine is the only one that will not run firefox. Sadness. Please help, pleeeease...

Win 7 with iTunes installed - I was also having problems with that.
"netsh winsock reset" at the command prompt resolved all issues and Firefox launched normally.
Check to see if Winsock is corrupted. May prevent FF from communicating with the web and consequently fails to launch properly - for my situation was not a firewall or antivirus block!
http://support.microsoft.com/kb/936211#LetMeFixItMyselfAlways
Click Start, and in Start Search, type cmd.
Right-click the cmd entry that appears in the search results, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
At the command prompt, type the following, and then press ENTER:
netsh winsock reset
Then, you should see the following message:
Successfully reset the Winsock Catalog. You must restart the computer in order to complete the reset.
Restart the computer.
Note If you receive an “Access Denied” error message instead of the message that is mentioned in step 3, the command prompt was not correctly elevated. In this case, close the Command Prompt window, and repeat steps 1 through 3. Make sure that you correctly implement step 2.

Firefox will not open Version 4.01 (tried to download new version), on MacBook Pro running 10.6.8. Safari and Chrom both work OK

I cannot get on-line with Firefox. It simply will not open any page. I'm told it cannot make a connection. And yet both Safari and Chrome work fine, hence it is not a connection problem.
Moreover, when I started with Chrome, it offered me the option to export bookmarks, but only from Safari. Firefox never appeared in the import box
I was using Firefox 4.01. I tried to download the new version, dragged it to Applications, but 4.01 remains in situ. I work on a MacBook Pro running 10.6.8

Cannot connect after upgrading Firefox

I wanted a solution to the problem I was having on Win 7 Pro Service Pack 1 in that links on an open Adobe Acrobat file will not open in my Firefox Browser 33.0.2. The Error I receive is "Acrobat could not run the web browser. Unknown Error. (123)"

Change browsers. See what happens.
