Uninstalled Bitdefender and restarted. No change. I can't figure out why the viewer stopped working one day during previous version, and still won't work in current version. I didn't change anything that might have touched on Calibre Portable, and I guess it wasn't Bitdefender.
I appreciate all the responses. Any other suggestions?
