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!

Hey billbuck99, Thank you for your question, this error was seen when there is a .parentlock file in the profile folder. There was also a bug that was fixed in the new version 30 that came out this week

Please terminate the process and update Firefox from the About Firefox page in the help menu.

Hey guigs2, how are you? I'm getting that same 'update could not be installed' message again when I start Firefox. I've updated to release 31 and reset to defaults but it's still there. Any ideas?

Many thanks

There are a few old methods for troubleshooting this but no longer maintained: https://support.mozilla.org/en-US/kb/update-failed-error-message-when-upd...

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-win...

I have this problem as well and the recommended fix does not work. My loaded version is: 32.0.2

I do not have Firefox in my C:\Program Files directory (oops!, I mean folder - I'm old and use old DOS terms), rather it is in: C:\Mozilla Firefox\

Is there something in the folder I can delete to remove this annoying message?
