Cannot connect to license server (-15, 570)

Causes: The license server process (

lmgrd.exe

) is stopped or disabled, or you are 

using the wrong license file for the Mathcad service.

Solution: Check the Services control panel for the license server process (indicated 

by the name specified in Step 3 of “Configuring the License Service” on page 16); 

if necessary, re-enable or restart the service. If the service is running, verify that it 

is using the license file supplied by PTC.

You may also have multiple license server processes running on the server. 

Consolidate all services under one license server process, or move the Mathcad 

license service to another server.
