In this article we explain the license manager error: 

This error will be reported in the geoslope.log file on the license manager if the license manager is running but the the Vendor Daemon (the geoslope-lmadmin service) fails to start.

Cause 

• The vendor daemon is experiencing a port conflict with other software running on the computer. 
• Often, the conflict is with another license manager that has the same default port settings as GEOSLOPE lmadmin.

Steps to Resolve

• The port conflict can be resolved either by making the GEOSLOPE vendor daemon port available or changing it to a different port.  See article:
  Changing the FlexNet Publisher License Server Manager Port Number
