Cannot Connect to the License Server
Symptom: When you start Creo View, you receive an error message in the Startup dialog box.
Cause: The license server is not running or the license client cannot reach the server.
Solution: Verify that the license server manager and ptc_d daemons are running. A network problem exists if a license client attempts to ping the server by host name and the ping fails.
