I have Ph.D. in Optical Sciences specializing in imaging, image processing, and image analysis. 45+ years of military, academic, and (mostly) industrial experience with image analysis programming and algorithm development. Experience designing custom light booths and other imaging systems. Experience with color and monochrome imaging, video analysis, thermal, ultraviolet, hyperspectral, CT, MRI, radiography, profilometry, microscopy, NIR and Raman spectroscopy, etc. on a huge variety of subjects.

Perhaps try putting all your calls to set in a single call to set() rather than a bunch of separate calls.

installation question. I downloaded for an offline installation since I have an installation key. However, when I run the installer from the downloaded files, nothing runs.
Call them on the phone and a real live person will talk you through it. They offer free installation help for everyone.
