Problem installing Jigoshop

Hello again,

I am attempting to install Jigoshop on my localhost (iMac running Mavericks 10.9.5) in order to attempt to install the drag & Drop Cart on a Jigoshop approved theme.

However i am getting this error:

Copied and Pasted from WP

WordPress database error: [Specified key was too long; max key length is 767 bytes]
CREATE TABLE IF NOT EXISTS wp_jigoshop_downloadable_product_permissions ( product_id mediumint(9) NOT NULL, user_email varchar(200) NOT NULL, user_id mediumint(9) NULL, order_key varchar(200) NOT NULL, downloads_remaining varchar(9) NULL, PRIMARY KEY id (product_id, order_key)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

WordPress database error: [Specified key was too long; max key length is 767 bytes]
CREATE TABLE IF NOT EXISTS wp_jigoshop_downloadable_product_permissions ( product_id mediumint(9) NOT NULL, user_email varchar(200) NOT NULL, user_id mediumint(9) NULL, order_key varchar(200) NOT NULL, downloads_remaining varchar(9) NULL, PRIMARY KEY id (product_id, order_key)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

We were not able to create a Jigoshop database table during installation! (jigoshop_downloadable_product_permissions)

End of Copy & Paste

I am installing from a WP downloaded zip for version Jigoshop 1.17.6

Thanks
