I want to use Draftsight 2020 in windows 7. I can't update the O.S. to Win 8 or 10 because I have a plotter that is not compatible with this O.S. 

Consider that I'd like to use Draftsight mainly for viewing and print. I think that i'd rarely draw with it.
Is it possible that Dassault will end the support for win 7 soon?
Thanks
