I tried several things from a search in Google regarding TLS initialization issues but they didn’t resolve when I tried to re-upload the upgrades - I still received the same error.
I have a full size laptop attached to my laser that I send jobs to the laser. My SurfacePro 8 doesn’t work to send jobs to the printer.
The upgrade happened without incident on that laptop and is connected to the same network as the SurfacePro 8.
Any suggestions that maybe helpful - Thanks in advance.
I just went thru the same issue on 1.5.01. Downloaded a new copy and it installed the runtime package first, then Lightburn. I did the Check for Updates and it downloaded 1.5.02 okay.
