"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'm using Firefox 4 Beta and I tryed install update but I dont got success. Now every time that I go start the browser is displayed the mensage: "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"
My release is installed not in default drive C:\. I installed in the other Partition on my PC.
I don't have other release installed.

Try a clean re-install.
- Download the setup file from http://www.mozilla.com/en-US/firefox/RC (this is for the Firefox 4 release candidate)
- Uninstall Firefox, do not select the option to "Remove my Firefox personal data"
- Delete the Firefox installation directory - http://kb.mozillazine.org/Installation_directory
- Re-install Firefox
This process does not remove the Firefox user data such as bookmarks and passwords which are stored elsewhere in the profile folder.
You may also need to manually reset the Software Update feature by deleting the software update files as shown in the "Software Update not working properly" section here - http://kb.mozillazine.org/Software_Update
Hello TonyE...
I did download and re-installed The Firefox. Lets to see if this solve the problem.
For now thanks for your helpful.
In Windows Vista or 7: a. close all Firefox by using task manager b. in Windows search dialogue box, type Firefox c. when Firefox appears in search results, right click, and select "run as administrator" d. you should see "update being installed" message (or something similar.
I followed what davidlum suggested above and this did the trick. The update installed successfully since there was no UAC dialog that needed to occur after running as Administrator.
I have since disabled the "Use a background service to install updates" (Options->Advanced>Update) to try and avoid this issue in the future.
