Hi Carlo,
Thanks! This script is now fixed in the source code repository.
I'm not sure what you mean by "installed the latest MySql version".
Note that if you are building from source code using VS, to use another data layer like MySql, all you have to do is choose the correct build profile from the dropdown in VS before building the solution, ie "Release - MySql" or "Debug - MySql". There is no need for any manual installation.
Best Regards,
Joe
