LDRA Test tools: FlexLM Error -31, Feature start date is in the future

22-Jun-2026

Cause

The feature you are trying to use has a start date set in the future. This can occur, for example, if an evaluation license was requested to begin on a specific date.


Solution

  • Wait until the specified start date, after which the license will become available
  • You can check the start date by opening the license.dat file in a text editor and searching for START=dd-Mmm-yyyy

If the license should not have a future start date, or your requirements have changed, request a reissued license without this restriction. Contact your local TASKING Sales representative or Technical support.
