I found a workaround to get it to show up as a webcam in Powerpoint. I installed Manycam and it now shows up as a webcam in Powerpoint with the Fujifilm X Webcam software installed, as well. The only issues is that Manycam comes with a watermark for the free version. I will test it and if it works well, I may purchase a license. In any case, Manycam seems to work like a link to other software that doesn't recognise the Fuji as a webcam. It now even works on the camera app in Windows.
