The installer says "'FF' is already running but is not responding. To open a new window, you must first close the existing 'FF' process, or restart your system." I have uninstalled it in all acocunts and there are no references to FF anywhere I can find, to include the Task Manager applications.

After the download,

  1. bring up the download manager ("Ctrl+J") and start your installs. As soon as the install comes up,
  2. close Firefox with File > Exit or "Firefox" button > Exit. Give Firefox some time to close.
  3. If install does not proceed, terminate "firefox.exe" and "plugin-container.exe" from the "Processes" tab in the Windows Task Manager.
    • Windows 7 shortcut to the WTM is "Ctrl+Shift+Esc"
    • or on any Windows system from "Ctrl+Shift+Esc" then choose Windows Task Manager.
    • Make sure that "firefox.exe" is no longer running -- if it is still running then terminate it by selecting the use "End Process" button or from context menu, and do the same for "plugin-container.exe" if it is found there.
  4. proceed with the install.
