Sorry. Acrobat is still up, pdfs are reading fine. Trouble is, there is no pdf for Hexagon. Used to be. I read it once! But since I purchased, there is no longer any sign of the one I was reading. Nor is there anything in the installer, the demo installer, or the patch installer. I've tried installing all three, again, in hopes they might deposit a pdf somewhere, and I've searched all my drives. If there is a manual now, it is well hidden.
