As many may know DelCAM has been bought by AutoDESK and they have gone to subscription licenses which require a yearly fee. I have 3 unregistered licenses for ArtCAM Express that are dongle free.
It is no longer possible to purchase ArtCAM Express 2015 R2, or any prior version of ArtCAM Express. ArtCAM 2017 will be available in three different variants: Free, Standard and Premium. The free version of ArtCAM 2017 is already available to download from the ArtCAM website. Free demonstration versions of Delcam’s ArtCAM Express and ArtCAM Insignia artistic CADCAM software are now available. Both programs can be downloaded from the www.artcam.com web site or obtained on a CD by emailing marketing@delcam.com.
