Expiry Dates for software licenses

When using a software license, each Build has a built-in expiry date that will prevent use after this date. This expiry date does not apply to USB License Keys. For two months ahead of the expiry the user is given a warning message, and for one month an extra dialog, to update to the most recent supported update. After expiry the user is given an "Error 733" requiring an update. This is simply resolved by updating from an old copy to the latest update for the Build (if staying with the same version); or the user can upgrade to the next version/build; or the user can use a USB License Key.

Expiry dates if using software license management:

  • Build 137.22530 or later - 25 September 2019
  • Build 137.21471 to 137.22529 - 25 March 2019
  • Build 137.21470 or earlier - 25 October 2018

Important updates after first release of SysCAD 9.3 Build 137.21484 (listed from the most recent to oldest)

Expiry Dates for software licenses

When using a software license, each Build has a built-in expiry date that will prevent use after this date. This expiry date does not apply to USB License Keys. For two months ahead of the expiry the user is given a warning message, and for one month an extra dialog, to update to the most recent supported update.

  • Build 20110: Improved dynamic mode display of tear convergence.
  • Build 20071: Fix for intermittent bad solution in simultaneous reactions. Because of uninitialised memory the simultaneous reaction solver can randomly occasionally fail which in a large project can cause a discontinuity.
  • Build 20044: Fix for crash on graphics page activate/deactivate.
  • Build 20035: Add option to SolventExtraction Isotherm to load or save curve data to csv file.
  • Build 20017: Correction in Hydrocyclone for calculating feed volume fraction used in Krebs method when using Alumina properties model.
  • Build 20013: Improved error reporting when makeup blocks are not connected to valid makeup source. Fix in dynamic where makeup in feeder did not give correct flow in first step.
