Just did a fresh install using the KDE for windows installer of Okular. When I try to launch Okular.exe from it complains with "The program can't start because libiconv.dll is missing from your computer ...". If I then go into bin and copy "iconv.dll" as "libiconv.dll", okular works as expected. Windows 8.1 64 bit Reproducible: Always
Current okular from craft seems to work fine for me. How to build: https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Windows Or grab it from https://binary-factory.kde.org/ or the Microsoft Store.
