You may see this error returned from both the Prizm Licensing Utility and 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.

There are a couple of options for resolving this:

• Requesting an Extension - Selecting this option will 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 within about one business day.
• Purchasing a Deployment License - You may visit www.accusoft.com for pricing information and to get in contact with Accusoft Sales about purchasing a Deployment License.
