To clarify, after I have nested the parts on a sheet I hit "Write NC" and a progress box comes up and just stays there with no progress been indicated and just stalls. Hitting "cancel" does nothing as the box still sits there replacing the "cancel" with a "aborting" prompt. The post processor that we use here is pdf32gen64.
We installed CAMduct 2018 on the laptop and copied our database over, the versions are the same but neither have had the service packs.
Thanks for reply and will be trying the service packs and look into getting 2021.
