Dear all, 

As Microsoft plans the end of life of legacy operating systems, DraftSight is planning ahead as well. Therefore, DraftSight 2020 will be the last release supporting Windows 7 and Windows 8.1 (32 and 64 bit). Please upgrade your operating system if you plan to use DraftSight 2021 or future releases.​​​​​​​This document shares more details. https://www.draftsight.com/sites/wp-fwk-ms-draftsight/files/2020-04/DraftSight_System_Requirements.pdf
