I am receiving the error below when I use my Toad For Oracle license key in Toad for Data Analysts.
Unable to validate license key. Reason: The value entered into the License Key text field may have been entered incorrectly. Please check the value for the License Key.
The Toad for Data Analysts installed is the Professional edition and not the Base edition one.
To verify this please go to Help | About.
The Toad for Oracle key only enables the TDA Base edition.
Uninstall the Professional Edition and install the Base Edition.
The base edition can be downloaded at: http://support.quest.com/Search/SearchDownloads.aspx
