BC Data Downloader not found.


BC Data Downloader not found! message appears when running BullCharts.

The BCDownloader is missing or has been removed. It is likely that an anti-virus programme has deleted BCDownloader.exe.  BCDownloader.exe  runs in the background to download the daily data and maybe regarded by some anti-virus programmes as matching the profile of a virus.


  1. Please upgrade BullCharts which will reinstall the missing file.
  2. To avoid BCDownloader.exe being deleted again, please add BCDownloader.exe as an exception as an allowed programme in your anti-virus programme.    Please check with the supplier to modify the settings.
  3. Change to a different anti-virus programme.  A few free ant-virus programmes are available.
