Can't access database with Local 5.0.6 on Windows

Local 5.0.6 does work on Windows, but I am unable to access the database either via adminer or ssh.

For instance, in SSH when I type wp db export, I get the following error:

‘grep’ is not recognized as an internal or external command, operable program or batch file.
mysqldump: Got error: 2003: Can’t connect to MySQL server on ‘localhost’ (10061) when trying to connect

When attempting to view via adminer, I get this error:

None of the supported PHP extensions (MySQLi, MySQL, PDO_MySQL) are available.

No database appears at all.
