Customer is getting invalid license key error when launching nuance template editor. Inside the error log it is showing Error 38: Communication to the license server is corrupted

Root Cause:

In one incident, it was due to the proxy setting that is blocking the license to be read.


If proxy is in used, configure the proxy parameters in the Nuance Licensing Tool. For checking the connection you can use the “Test Connection” button in the Configuration pane.

This should resolve the issue.
