You may see this error returned from either the License Manager or the Evaluation Licensing website. It means that you have previously obtained an Evaluation License for your machine, using your Evaluation e-mail address, which has since expired.

To resolve this issue, you can do one of the following:

• Request an Extension - Select this option to send a request to Accusoft Sales to extend the evaluation period of your license. These requests are reviewed by Accusoft Sales staff, and are usually processed in approximately one business day. 
• Purchase a Development (Toolkit) License - You may visit www.accusoft.com for pricing information and to get in contact with Accusoft Sales about purchasing a Development License.
