I had the same problem after upgrading to the latest version. After lots of trial and error, what i had to do to fix it was. Uninstall, search my C: drive for every leftover file with "XNview" in the name, and delete those. then I downloaded and installed older versions, redoing the uninstall , search for files, and delete them process, until I found one where it worked again. in my case version 2.50.4
