I have this same problem. It is quite annoying. It was there in PD15 and I eventually decided to upgrade to PD16 hoping Cyberlink would have fixed this. They have not. PhotoDirector finds the browser (either Edge or Chrome, whichever I have as default at the time). Likewise AudioDirector and ColorDirector. Why can't Cyberlink just pick up their code and shove it into PowerDirector??? I cannot accept "use IE" as the answer, given that it is an unsupported, obsolete browser that Microsoft do not want us to use.
