What can i do about this problem? I click "more details" and find out that the 'unknown program' is firefox. I click to install; but windows does not allow the updates to complete. I let the update window run for over an hour one day... it still did not complete.

Check that you do not run Firefox as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

  • Privilege Level: "Run this program as Administrator" should not be selected
  • "Run this program in compatibility mode for:" should not be selected

Also check the Properties of the firefox.exe program in the Firefox program directory.
