On starting FF, get error 'the update cld nt be installed.Make sure no other copies running' even from cold. Have reset but still persists.

On starting Firefox (Windows 7), even from a cold boot I get a dialogue box with the message 'The update could not be installed. Please make sure there are no other copies of Firefox running on your computer and then restart Firefox to try again'
I have checked task manager and there are no other copies.
I have downloaded the latest version 29 Firefox but the error persists.
I have reset Firefox to default state but the error still persists.
Help please!

There are a few old methods for troubleshooting this but no longer maintained:
[https://support.mozilla.org/en-US/kb/update-failed-error-message-when-updating]
Sometimes there are other programs that might be preventing the update, as well as a need for a clean reinstall. However it is odd that this has happened two versions in a row. Does your firewall or antivirus allow updates to Firefox? [http://kb.mozillazine.org/Firewalls]
If you restart the computer does the error message still happen when you try to update from the About Firefox page?
A manual installation can always be done [https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-windows]

Update could not be installed pls make sure no other copies running

I have version Firefox 10.0 and it is trying to update to 10.0.01 but msg states update could not be installed. Please make sure no other copies of FF are running. I had this problem before V10 was updated and re-installed FF at that time. Why does this continue to happen. I tried restarting and Run as admin but nothing works.

Hi,
Please try deleting the '''parent.lock''' file in the [http://kb.mozillazine.org/Profile_folder Firefox Profile Folder]. You can also open this folder via Firefox '''Help''' ('''Alt''' + '''H''') > '''Troubleshooting Information''' > '''Open Containing Folder''', and exit Firefox.

With the latest update I get the following error: The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again; suggestions, advice, help.

Help>About Firefox> says I am using Firefox/3.6.10./GTB7.1 I get a note from Mozilla that there is an update. I download it after granting permission to change my machine. I say OK. A green bar slides across the monitor announcing that the update is being downloaded. When I then assume it is being installed I get the following error: The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again. There are no other copies running. The machine is not on a network. I am using WIN7

Thanks for the info about Trojan. It may be the problem. Meanwhile I went to Admin/Owner side and did some cleaning -- including trying to reload my Favorite/Bookmarks that have always carried forth from previous levels of Windows XP and earlier.
The new computer here did not grab the Bookmarks from the previous, and yesterday I thought I had them loaded, and today went to Worker-Bee side and they are not showing.
About those add-ons... I have no idea, but think I got everything up to date yesterday. I will look at your earlier reply tomorrow or this weekend when I have more time at home to learn from it.
Thank you for your time in helping.
Late here, heading to sleep. Marilyn

While attempting to update my ipad2 with the 8.1.3 update, screen froze towards the end of the update. Tried to turn it off by holding power butter to do a hard reset, but it won't turn off. How do I fix this?

Have you tried a soft-reset : Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should reappear and it will hopefully reboot.
If that doesn't work : If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

Update could not be installed. Make sure no other copies are running. Same over and over.

Firefox keeps trying to install update. Message: Update could not be installed. Make sure no other copies of Foxfire are running then restart FF to try again. Repeats same message over and over.

Firefix claims an update is available, and so I click to get it installed (I am running 5.0). I get a message that the install failed and that I need to make sure no other copies of FF are running on my computer. ??

The bigger issue is that it tries to run the update every time I click on a URL (like from an email). And so it opens a window to locate a browser, then starts the update - which then crashes with the message about making sure no other copies of FF are running.

My auto update is failing. I tried reboot and run as admin, but did not help. I get message: The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again.

I followed the instructions on the support page. I did a Windows restart. I cannot see how other copies of Firefox could be running. No other apps have been launched and Task Manager only shows one copy of Firefox and no other apps. I have tried several times and always get the same result.

Win7pro update error: The update could not be installed. Please make sure there are no other copies of Firefox funning on your computer, and then restart Firefox to try again.

Receiving error message when updating FF6, and then after installing a fresh copy of FF7, when FF tried to update again.
This is happening with FF that is installed on my machine and with FF portable. Has anyone else experienced this?

Error: ' The Update could not be installed (patch apply failed)' . It keeps trying to install this patch but my version is the latest one!!

I have the latest version of firefox. I know this because your website says so. But for some reason, my current firefox keeps trying to install a new version by "trying" to install a patch. But it fails every time.
I cant say exactly when this started. A few weeks ago, firefox was behaving erratically (crashing for no reason at every launch due to some video plugin fail) but i uninstalled and reinstalled (a few times) and it was fine after the last one.

If files already have been downloaded then remove the files in the updates and updates\0 folder.
You can also delete the active-update.xml file.

HT6058 I started to down load the update and (7.0.4) and got disconnected now my Iphone 5 is looking for itunes but I can not log on because my hotspot is on the phone. what do I do?

My phone started to download IoS 7.0.4 with my hotspot on the phone from itunes. I have no internet connectivity and the phone will only display connect to iTunes on the screen. What do I do?

You will need to find a place where you can connect the computer to the internet so you can restore the iPhone - no way around that at this point.
Were you using your iPhone's hotspot as the internet connection for the computer to download and install an update on that very same iPhone that was providing the internet connection? If so, honestly, that was not a smart thing to do at all. In order to apply the downloaded update,the phone had to restart and disconnect - it could not possible install an update without doing that.
Regardless, it is now in recovery mode. The only way to recover it is to restore it with iTunes on your computer and that will require an internet connection.

FF7 update error: The update could not be installed.

Firefox is not succesfully installing updates. If I download the newest version, it installs fine. Downloading and applying the update on it's own fails.
Has anyone else experienced this?

Check and tell if its working.

When opening Firefox Mozilla,the following message appears -Update could not be installed.Make sure there are no other copies of Firefox running on your computer & then restart Firefox to try again.

If there are other copies of Firefox running, do not know how to check.

You may have to disable ZoneAlarm ForceField to be able to install Firefox.
If you use ZoneAlarm Extreme Security then disable Virtualization and reinstall Firefox.
Other security software may have similar features to prevent Firefox from updating files properly.

How do I remove items from the right side of the menu bar in Lion? I'm speaking of old software items that I have deleted but still have an icon there. Holding the "Command" key and dragging them out doesn't work.

I have icons left over from trial software I have deleted in my menu bar and can't get rid of them. I've tried dragging them out while holding down the "Command" or "Control" keys but that didn't work.
