Set Environment Variable

You can set a License Key as an environment variable. There are two environment variables available for Address Object: MD_LICENSE and MD_LICENSE_DEMO. These environment variables were made available so that you can change certain aspects of your applications without recompiling. You can set these both MD_LICENSE and MD_LICENSE_DEMO as environment variables at same time. If you are using variable MD_LICENSE for any other product then you can use MD_LICENSE_DEMO for Address Object or vice versa. Don't get confused with the word "DEMO" for a valid License Key, it works same as MD_LICENSE.

Linux

1. Go to the console of your LINUX Machine.
2. Write the following command in your console, it will set one License Key for all the Melissa Data Objects installed on that machine ‘export MD_LICENSE = “XXXXXXXXXXXXXXXX” ’

You can use variable ‘MD_LICENSE_DEMO’ if you need to use another License Key for Melissa Data Objects.

(To set environment variable permanently for LINUX you need to add this in your profile.)
