Only CorelPaint cannot open pictures from the new iPhone7 that uses an iSight camera lens. In fact, it causes your computer to crash. And a fix is not in sight.
It would be wrong for Corel to ask users to pay for an upgrade, but they just might.
From what I have seen, they just discovered it and do not seem to be in much of a hurry to fix it. Level 1 tech support staff seem to be ignorant about it. I had to escalate to Level 2 to find out about it. It took a couple of dozen emails for me to get there.
However, I can open such pictures with competitors’ products such as Adobe Photoshop.
