RAW Codecs Windows 8
Just a follow-up. I re-installed Windows 8, and then installed my software with what I considered the safest first. After each installation I'd check to see how it was doing. I got down to nothing left to install but FastPictureViewer, took a deep breath, and installed it. No problems.
I don't know what killed my graphics on the applets--or whatever they're called--but whatever it was wasn't the raw codecs.
