Our company has been using Draftsight for a while and recently, we were affected by the 2017 expired certificate issue.  This forced us to upgrade all of our computers (we opted to update the software, rather than just patch the old release). 

However, I now have the unfortunate situation of a couple  off-network computers that I need to work with Draftsight, which are not working.  The computers are not network connected and cannot be network connected.   I am unable to get past the activation screen on the latest release of the installed software.

 My question is as follows:  Can I get the new version of Draftsight Free to work offline, or must I purchase the professional version to enter a key code to activate this computer?

 I look forward to your input on this.
