Tried, I still get this 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.

See http://kb.mozillazine.org/Software_Update (Software Update not working properly) Remove the files in the updates and updates\0 folder:

C:\Users\<user>\AppData\Local\Mozilla\Firefox\Mozilla Firefox\updates
(%LOCALAPPDATA%\Mozilla\Firefox\Mozilla Firefox\updates)
C:\Users\<user>\AppData\Local\VirtualStore\Program Files\Mozilla Firefox\updates

Download a fresh copy of Firefox ( http://www.mozilla.com/firefox/all.html ) and do a reinstall of Firefox over the top of the current version. If that still causes the same problem then do a clean reinstall.

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

If this occurrence is happening to those who are running windows 7, go to the install directory usually C:\Program Files\Mozilla Firefox\firefox.exe right click the firefox icon and select run as administrator and your update will install and all will be normal again.
