August 14, 2017 - Version 15.09 of DESIGN II for Windows is available for download now ! This is a release with both fixes and upgrades.
  • Significantly sped up the loading of large Flowsheet files with thousands of equipment modules and streams.
  • Fixed the loading message box from being destroyed and recreated between each DataSet loading from a Flowsheet file which was causing flashing.
