Please provide a screenshot of the warning messages you've encountered when trying to install ArtCAM Insignia 2015 R2.SP3 (64-bit build 860).

The original Artcam installation was from my disc. You are correct SP3 860 I downloaded twice This happened the first time corrupt files so I stopped the installation, download again the following evening the same thing was about 8 or nine times that a corrupt file warning came up.
