Error message :"C:\Program files (x86)\Mozilla firefox\firefox.exe......The application failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail" How can I fix this error and go back to firefox instead of connecting through IE? I try to reinstall firefox, however I received the same message
