I'm using IE to download firefox 3.6. I click run to download, click run for setup. Then it says it must close to finish a previous uninstall. I get the firefox.exe icon but each time I try to run it, I get the above message and then it reboots but trying to run firefox is the same.

See:

Remove the files in the updates and updates\0 folder: 

C:\Documents and Settings\<user>\Local Settings\Application Data\Mozilla\Firefox\Mozilla Firefox\updates
(%USERPROFILE%\Local Settings\Application Data\Mozilla\Firefox\Mozilla Firefox\updates)

Do a clean (re)install:

  • 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.
  • Don't remove personal data if you uninstall the current version.
  • 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.

Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
