I just followed this discussion, following a problem with the activation of Draftsight.
Like you, following a recent update of Windaube 10, it is impossible to use Draftsight 2017SP2 which worked well until now.
I went to the official website, and I downloaded the latest SP3 version released recently, but again, after installing, I couldn't activate it. As you do, the software launches, asks for all the email address bazzar, and then closes, without saying thank you or goodbye... Of course, no answer on the address indicated.
After following this thread, I deactivated my Avast antivirus, filled in the email address and others, indicating "Andorra" instead of "France" (you never know), and there it went like a letter in the post office (when it's not on strike) with a nice message of explanation. I received an activation email within 20s and here we go again...!
Hoping that this experience can serve you. Have a good day everyone.
So I'm on windows 10 - 64 bit. I had the same problem as everyone else when activating. Problem that I solved simply by launching the installation and then the activation in safe mode with network support.
Only since then it's been dragging to death on the software. I can't find any solution to this problem, which wastes precious time; So if anyone has a solution I'm interested.
