I am having the same problem others are having with the activation of draftsight. I had 2023 installed, then updated to 2024, and now I am unable to activate draftsight. I get the same error messages as the others:

"The current computer identifier (0) does not match the previously used computer identifier (1). You can continue, but you might have activation or deactivation issues in the future. please contact *you* support representative for support." 

I have submitted a support request twice and still have not received a reply. the other message is:

"Activation transaction failed: Activation count exceeded. Deactivate a license from another computer and retry. Visit My.SolidWorks for more information. (3/0)"

My auto payment for mu subscription just went through Thursday but I have not been able to use draftsight in a week or more.
