The most common reason lately for this error is Windows 10 automatic updates, or possibly Windows 7. If you are willing, the easiest way to avoid this is to disable automatic updates.

Disable Windows 10 automatic updates


The first thing to try to remedy it is to uninstall BioExplorer and Hasp device drivers and reinstall

  1. In your search field type add or remove programs and select it
  2. Select BioExplorer from the list of programs and uninstall
  3. Select Hasp device drivers from the list and uninstall
  4. Download the latest BE Setup file from, saving it to your computer
  5. Right-click on the setup file and run as administrator

Other ways this has been remedied:

  • Revert to previous build
    • Restore to previous point when it worked
    • Remove update from control panel "Add or Remove Programs"
      Microsoft's semiannual major build may not allow this
  • Do a system refresh which removes non-Windows programs but leaves files
  • Do a system reset. You will need to back up your files for this.
  • Restore to factory settings
