I have been using the PREVIEW PANEL for a long time, and it always launched the application inside it if i wanted to preview it (musics or video or Excel or PDF...). That is if I was exploring a folder and its file and there was an Audio or Video file it would be LUANCHABLE in the right preview panel of Explorer. Now lately somehow something changed and when I explore, the photo or image will show up in the PREVIEW PANEL, but for instance video, audio files will not launch I have to click on it and then the associated application opens up to play whatever it is I clicked on. I also used to be able to preview EXCEL WB there, now nothing it says PREVIEW not available.
Can you please let me know where and how to reset that up properly?
