Receiving this error during the database setup indicates that you are attempting to install the Blue Prism Trial or Learning Edition on a Windows computer which is not supported.
You can only install Blue Prism Trial or Learning Edition on a 64-bit installation of Windows 8.1 (or above).
Support Center: Why do I get error "The procedure entry point BCryptKeyDerivation could not be located in the dynamic link library bcrypt.dll" when setting up the Blue Prism Trial or Learning Edition?
Ok, Windows 7 will be your problem. Trial and Learning Edition requires Windows 8.1 (or above). Windows 7 is therefore not supported because the Microsoft SQL Server LocalDB that we setup for you will not work on Windows 7.
