Windows DEP will not allow Firefox to load

Been having trouble for some time with Firefox crashing in the middle of sending emails. Downloaded Vers 4 with a hope this would stop. This haven't and today Firefox has crashed some 4-5 times in less than 1 hour. Rebooting PC doesn't help. Following latest crash Firefox will not load not even in safe mode. Now getting Windows msg Firefox has stopped working check online or close the program. Check online gives the msg application failed to initialise properly - click ok to terminate. Have also had a mge stating that Windows DEP (Data Execution Prevention) has seen that Firefox may be a virus or a security threat and that it's attempting to run a program from memory restricted for use by other programs. See DEP in Windows help. unsafe and has closed the program

In the URL field, type: '''about:crashes''' and hit Enter. Then choose the most recent crash (they're links, so click them). You may possibly find some insight into the problem.

Help I have installed and reinstalled iTunes but it will not open. I get an error telling me that windows DEP will not allow the program to run and i can not shut the DEP off for the program. i need to reset my ipod touch and cant cause of this.

I have tried to shut off the DEP for the program but it is not allowed. I can't get to any of my music on my computer because of this. I use windows vista and was able to use ITunes until the upgrade to 10.2. now i can't even open the program and it is getting me very upset. Please someone help me.

Many thanks.
That suggests that another application has stashed old QuickTime componentry in your system files.
So just in case we'll go looking for older QuickTime componentry in the most common locations for it to be stashed.
First we'll need to change some view settings.
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.
Now in Computer, open your C:\ drive (or whichever drive you have your operating system installed on).
Open the "Windows" folder.
If you have a 32-bit version of Windows, open the "System32" folder.
If you have a 64-bit version of Windows, open the "SysWOW64" folder.
What files and folders can you see in there with QuickTime in the title? (In a standard installation of Quicktime you should be seeing precisely two files... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)

My system needs internet explorer for a application I need to down load, however I need to down load the latest yahoo tool bar for internet explorer to work properly and firefox will not allow the down load of yahoo toolbar. How do I fix this?

I have not used Internet explorer since downloading firefox and I need IE for a trading platform that I need to use. In order to get IE working I apparently need to down load the latest version of Yahoo toolbar, however when I try to down load the tool bar Firefox will not allow the down load of that file.

Thank you so much, for once in my computer life I knew what the problem was, what caused it, why it was caused, what it did, what it made it do and most importantly how to fix it and to do it correctly and expeditiously. I can not Thank You all enough for all of the help! I also have Pogo mailed this to all on my friends list, where they have all learned as I have and have fixed theirs also. and the message is being spread. Thank You again, I just can not say it enough.

My DVD drive on my IMAC will not allow me to load a disc, even though there is no DVD in the disc slot.

My IMAC will not allow me to load a DVD, even though the disc drive is empty. Any ideas as to what I should do to resolve the problem
Thanks
Roger

Sounds like you have a newer iMac than this forum covers. The newer ones have a bar or "fence" that, on detecting the drive has failed. moves the bar to block the slot so no media can be inserted (to avoid damage or loss of a disk).
You will need a new optical drive--contact an Apple retail Store or an Authorized Apple Service Provider:

I was going to ask a similar question - we bought the boxed version of PSE11 with mac and pc disc - can we install the program on our mac as well as our PC? It's already on the PC but would be very handy to have it on Mac also. Thanks

Trying to repair iTunes on Windows Vista will not allow to do so except to uninstall it

Trying to repair iTunes on Windows Vista. Will not allow me to do it. I've followed the instruction to select the programme in control panel, the select 'repair', unfortunately, the only option available to me is 'uninstall.' Therefore, I tried to uninstall with a view to reinstalling the whole programme but it wouldn't let me do this either because the .msi file could not be found.
Can anyone out there help??
Regards
geordiejohn65

Therefore, I tried to uninstall with a view to reinstalling the whole programme but it wouldn't let me do this either because the .msi file could not be found.
(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?

TS3212 windows dep will not let me run itunes

windows vista will not let me open i tunes dep message can anyone help please

Try updating your QuickTime Player to the most recent version. Does that clear up the DEP errors in iTunes?

Internet Explorer has overridden Firefox and will not allow it to load

I followed an update prompt for Adobe Reader and now Firefox will not load at all. All Firefox icons go directly to IE. I uninstalled and re-installed Firefox with no luck.

Hello.
Have you tried running Firefox's executable directly? It's usually located at ''C:\Program Files\Mozilla Firefox\firefox.exe'', but it may be somewhere else, if you installed Firefox in another location.
Please report back the results.
And by the way, you can always create new shortcuts, if running the executable directly does the trick.

Data Execution Prevention (DEP) has not allowed firefox to start, even after reinstalling firefox

Firefox will not start. Windows message tells me Data Execution Prevention (DEP)has prevented this program from starting. Help says: If DEP notices a program on your computer using memory incorrectly, it closes the program and notifies you.

Try updating your QuickTime to the most recent version. Does that clear up the DEP errors in iTunes?

I updated to iTunes 10.5 on Vista. As with iTunes 10.0, The DEP will not allow iTunes to open. WHEN IS APPLE GOING TO ADDRESS THIS ISSUE? I can't update my telephone or iPod. I can't even open the iTunes program!!!

I am sick of dealing with this issue. I wish not that I had never even started using any Apple products, beginning with iTunes. WHEN IS APPLE GOING TO ADDRESS THIS ISSUE AND MAKE ITUNES SOMEHOW COMPATIBLE WITH DEP IN WINDOWS VISTA?
That being said, Is there any way to resolve this? What I did in the past is completely wipe ALL Apple files from my computer, and install an older version of iTunes. It was at least functional. It seems that any version of iTunes 10.0 or more recent is not compatible with the Data Execution Prevention in Windows. You can not remove iTunes from DEP, yet DEP prevents iTunes from running.
The down side is that I can't get the latest updates for my iPhone or iPod. Now, I have a new phone for my husband that needs syncing on my iTunes, and I can't do that because iTunes won't even open.
Can somebody help me out with this, please?

OK, lets do a complete overhaul to make sure it's working ok.
First to check your Windows system file for any corruption:
Go to command prompt (START/ALL PROGRAMS/ACCESSORIES right mouse click "command prompt" and choose "Run as Administrator"
type in
sfc /scannow
let Windows fix any system files that need to be repaired.
Restart the computer.
Start iTunes and see if it is ok.
If it doesn't, will have to go through the whole process of uninstalling and installing acccording to the following steps:
1. Go to Microsoft website to fix install and Unistall problems. Click "Run now" from Fix it to remove all iTunes & related installer files:
http://support.microsoft.com/mats/Program_Install_and_Uninstall
Be aware that Windows Installer CleanUp Utility will not remove the actual program from your computer. However, it will remove the installation files so that you can start the installation, upgrade, or uninstall over.
2. You should remove all instances of iTunes and the rest of the components listed below:
it may be necessary to remove all traces of iTunes, QuickTime, and related software components from your computer before reinstalling iTunes.
Use the Control Panel to uninstall iTunes and related software components in the following order:
iTunes
QuickTime
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
(Referenceinstructions from Apple article listed here: http://support.apple.com/kb/HT1923 to remove all components)
3. Reboot your computer. Next, download iTunes from here:http://www.apple.com/itunes/download/ and install from scratch

Windows 7 will not allow a high resolution for my apple 30" monitor?

For some reason I cannot change the resolution on my 30" monitor as high as I can on my 23 inch monitor. This results in super big windows and font 4 times the size of the 23 inch monitor. My IT searched for a driver but could not find one. I used to use windows XP and he did find a driver for that. Anyone know where we can find the right driver to solve this problem. The video card is a Radion. My computer is a 3 year old Mac Pro..
Thanks in advance!

Recently I purchased an alienware M18 laptop installed with Windows 7 . I wanted to downlode the latest Itunes to this system as I have on other comptures I own. Itunes dowloaded and is accessible to a limited degree . What it will not do is provide access to the Itunes store. Something is blocking my access to the Itunes store and I have benn unable to determine what the obstruction might be.
If it's an alienware PC, plausibly you might be getting the Bigfoot networks variation of the problem described in the following document:
iTunes 10.5 for Windows: May see performance issues and blank iTunes Store
If it is the Bigfoot networks variation, stopping Xeno NIC from running at startup is worth a try, as per John's post here:
Re: Safari Not working at all! (Windows 7)

Windows 7 will not allow me to recovery to factory settings

MY DVD's will not work to recover system setup. F11 does not work at all .. I still have the recover partition on my hard drive... Should I reformt my hard drive and use my recovery disks to get back Vista ??? This is a good one... Can someone please help me ....
This question was solved.
View Solution.

You can try this...it might work if you've not deleted the "hidden" files.
Boot to the desktop, go to the start menu, right-click on "computer" and select manage.
This will launch the Microsoft Management Console.
On the left side of the MMC, click on "Disk Management" and then it will show you all of the partitions and hard drives in the unit.
Right-click on the "HP Recovery" partition and select "Mark as Active Partition."
When the warning prompt appears, select "Yes" - Then reboot the notebook and it will automatically boot into the Recovery Manager without having to press F11.
Perform the recovery as usual and then everything will be normal again.
This will only work as long as the Recovery Partition hasn't been modified or the "Recovery" file deleted.
If you can't get to Disk Management following the instructions, try this article for help finding it.

When i try to open firefox i get a message that says Windows has encountered a problem and will notify when there is a solution. Then you can click on the explanation and it says DEP will not allow it to open. Can you tell me how to fix this?

I was able to install and have an icon on my desktop. When i click on it it automatically pops a box up that says: Firefox has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. Then it highlights an icon at the bottom to show what the problem is and it is DEP (data execution prevention. I tried a few suggestions there but it didn't work. So it said to see if there is a download version compatable with DEP

Windows Explorer will not allow me to download Firefox. Suggestions?

I am running Windows 7 and Internet Explorer. When I attempt to download Firefox I receive an error message saying that Firefox can not be downloaded. I have tried the usual fixes by disabling my anti-virus program and disabling certain download buttons in Explorer but without success. Any suggestions? PS: It's a Dell computer still under warranty but when I called them for assistance they wanted $249.00 to assist me. So much for the great tech support and customer service they offer!!!!!

A possibility is to open the Mozilla FTP website in <u>Windows Explorer</u> and download the Firefox set up file that way.
See "How To Download Firefox On a New Computer Without Using Internet Explorer":
* http://www.howtogeek.com/125447/
* ftp://ftp.mozilla.org/pub/firefox/releases/latest/win32/en-US/
Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
