If you already have Courier 2.0 installed, follow these steps to upgrade to 2.x:
Update the /config/courier.config file with settings from your backed-up one.
If for some reason the package installation fails or due to permissions or other reasons is not an option on your system, we provide a manual installation process.
To manually install, download the manual install package from umbraco.com or one of the hotfix releases from nightly.umbraco.org
The manual process consists of several files:
Simply unzip the /bin, /config and /umbraco folders to the root of your website, the archive follows the structure needed to place the files correctly. Notice: the archive assumes your Umbraco director is located at /umbraco. If not you will need to move those files manually to the right location.
If you have purchased Umbraco Courier, you can download a license file on umbraco.com. This license file must be placed in the websites /bin directory to be registered.
To install the database we need to execute a sql script against the database Umbraco is installed on. Courier currently only supports SQL server 2005 and 2008.
If any errors are displayed, check your permissions. The install script requires database owner access, as it creates new tables.
In case of error you can use the /sql/uninstall/uninstall.sql file to remove all courier tables. Follow the same procedure as the one describing "installing the database"
