it states a previous update needs to take effect and a reboot is needed. but nothing happens. pc reboots, i try to launch firefox and it asked the same question to reboot. tried uninstall and the same thing happens. help. Tried looking for the xpicleanup.dat file to remove as stated in help files, but no luck either.

hi mate, yep looked at that and hit the link of needs to update before installation can occur.

tried the %data% thing. even used search to find the xpicleanup.dat file.

came up with nothing and it still tries to update a previous version if i try to start it or uninstall it.

cheers

If present it would be in the Mozilla Firefox folder in Program Files (x86) assuming that Firefox was installed in the default location.

See the Latest Firefox issues article. Try the first suggestion, to download the Firefox installer from mozilla.org/firefox and then reinstall Firefox (see How to install Firefox on Windows for detailed instructions).

Thanks for reporting that deleting the file firefox.exe.moz-upgrade fixed it. I'll mark your reply as the solution.
