Certified CSI for UR here. I have several machines deployed that are running older versions of polyscope. I need to utilize the offline simulator to help them troubleshoot issues/push updated programs to them. I cannot find older versions on the UR Downloads site. I only see 5.12 and the newest versions. I am sure the typical response is: have your customers update their polyscope! This is easier said than done. Is it possible to get the older versions of the URsim? My immediate need is for v 5.13.0 Are there other versions of URSim that are guaranteed to be compatible with v5.13? If so what are they and are they available on the sim? Thanks, Evan ---
