SAM database error on startup

I’ve attempted a re-install with SAM BC using a MySQL database and of course downloaded MySQL, but still i get the error message that “the requested database driver could not be found”. Here are the details.

Protocol- MYSQL
Hostname- localhost
Database- C:\Program Files\SpacialAudio\SAMBC\libmysql.dll
User- ****
password- **********

Really stuck on this now :\

Thanks.
