ERROR Registering: C:\Program Files (x86)\Mozilla Firefox\AccessibleMarshal.dll and failure to install

I downloaded and extracted the latest ESR file (Version 10.0.7) this morning. Running SETUP.EXE with no command line switches fails to install Firefox. Ths installation log indicates that the installation has taken 1 second to complete execution. In the Installation log I see the following:
DLL Registration
** ERROR Registering: C:\Program Files (x86)\Mozilla Firefox\AccessibleMarshal.dll **
In the C:\Program Files (x86)\Mozilla Firefox folder there is an uninstall folder as well as an install.log file. No other files or folders exist. Mozilla Firefox does appear in the Programs and Features but shows an icon associated with an unknown application.
I am logged in with a low-rights account but running the SETUP.EXE executable from an elevated command prompt. This should be sufficient to elevate the DLL registration.
Running on Windows 7 SP1 with all applicable updates. I've noticed several other people that have experienced this issue but nobody has a solution.
Thanks in advance for any help!

When I click on my Firefox desktop shortcut, this message appears "The application or DLL C:\Program Files\Mozilla Firefox\MOZCRT19.dll is not a valid Windows image. Please check this against your instillation diskette". I cannot enter the program.

I believe that my question gave all the details. I am wireless in my home and the other computers connected to this wireless have no problem getting into Firefox. What is MOZCRT19?

clementem,
This means there is a problem with the files you need to run Firefox.
Try a clean reinstall:
1. Download the Firefox installer from [http://mozilla.com Mozilla.com] and save it to your desktop or other location.
2. Make sure that Firefox is closed completely
3. Delete the Firefox installation directory (On Windows, this is typically the C:\Program Files\Mozilla Firefox folder that contains "firefox.exe" and other Firefox program files and folders).
4. Reinstall Firefox by running the installer you downloaded previously.
Your personal settings, including bookmarks and history, will not be lost.

I was in Firefox but I exited. Soon I opened it again, it
installed updates and this message showed up. I tried
scanning the file, looking at it, and everything short of
reinstalling Firefox (which every other person with this
problem has tried but it has not worked.). I installed
Firefox by USB drive, not a diskette, and I no longer have
it with me, so I can't check it from there. What should I
do to fix this problem?

Am getting this message when I attempt to open Firefox: "The application or DLL F:\Program Files\ Mozilla Firefox\nss3.dll is not a valid Windows image. Please check this against your installation diskette."

I had responded favorably to the upgrade message from Firefox but after the download I kept getting a Firefox message that I had to close all other instances of Firefox running before the installation process could complete. There were no other open Firefox programs! I re-booted and tried to open Firefox, and the Windows alert already cited started, and Firefox will not open.
Checking via Windows Explorer it appears that I still have version 3.6.

I resolved the problem. I went to CNet and re-downloaded the upgrade. It proceeded as intended and the upgrade is installed and running with no loss of plug-ins, bookmarks, etc.

I just had a screen pop up from Mozilla Firefox. Warning: system may have found viruses on your computer.

hello, mozilla will never send out such kind of popups - this is a scam trying to trick you into downloading more mailcious stuff. in case you're getting such kind of pop-ups regularily though, this by itself might be a symptom that there is already adware/malware present on your system.
 in this case please try the following:
# [[Reset Firefox – easily fix most problems|reset firefox]] (this will keep your bookmarks and passwords)
# afterwards go to firefox > addons > extensions and in case there are still extensions listed there, disable them.
# finally run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] to make sure that adware isn't present in other places of your system as well.

Hi,
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:
* [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner]
* [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware]
* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
* [http://www.surfright.nl/en/hitmanpro/ Hitman Pro]
* [http://www.eset.com/us/online-scanner/ ESET Online Scanner]
[http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.
Further information can be found in the [[Troubleshoot Firefox issues caused by malware]] article.

Hope this helps!

Any Mozilla product I install crashes at startup. The first window I see when I open a Mozilla product is the crash reporter. I have tried every possible solution but cannot open anything. It started with firefox. Can anyone please help?

Hi there, as the question says, I cannot open any Mozilla product. I have tried to install firefox 3.6, older versions of Firefox, Firefox 4.0, Sea Monkey, Thunder Bird and Sun Bird. I have the same problem everytime. I open any of these programs and the first and the only window that appears is the crash reporter. I've tried opening it in Safe Mode and the same occurs. I have tried entirely uninstalling the products incuding the registry keys but no help. I shall post the detailed error reports, if they help solving this issue. Can you kindly look into this and find a solution as I use all of these Mozilla products and my life has been a hell since they've ben down.

Same problem over here as well, FF 7 is ok but FF8 / FF9 and Thunderbird 8 / 9 crash on startup.
They both work if I start them in safe mode with everything enabled.

ESET NOD 32 cannot scan past this point. I keep getting stuck at 56% at the following; C:\Documents and Settings\Owner\Application Data\ Mozilla\Firefox\Crash Reports\Pending. Is this a problem with NOD32 or with Firefox? Thank you.

I ran into a glitch on my system that I tried to fix myself. My NOD32 was always showing the yellow warning circle as my protection status when I started my computer. I tried to fix this every way I new how.
Then I started to get pop ups asking me to fix and then send system error reports to Windows. Some stating they were '''''critical.''''' So I sent NOD32 the e-mail below.
'''Me:''' I cannot seem to run a complete system scan. I keep getting stuck at 56% at the following point. C:\Documents and Settings\Owner\Application Data\
Mozilla\Firefox\Crash Reports\Pending
I also keep getting messages to send error reports to Microsoft constantly. I also have this code C:\pagefile.sys-error opening
Thank you for your assistance.
'''Their solution:'''
Based on the information you provided, we recommend that you upgrade to latest version of ESET NOD32 Antivirus and see if this makes a difference.
Please click or copy/paste the following ESET Knowledgebase article into your web browser for step-by-step instructions:
'''Me''' : I did as they requested and am fully upgraded and licensed with their new edition.
Ran a new scan same problem.
I sent them a new e-mail but now wonder if it is a Firefox issue as, C:\Documents and Settings\Owner\Application Data\
''Mozilla\Firefox\Crash Reports\Pending'' this is where the scan stalls.
Any help would be appreciated.
Thank you.

Try delete the files in Pending folder and make the scan again, do not be afraid to delete the files see : https://support.mozilla.org/en-US/questions/679996
thank you
