WSJT-X V1.7 (available now from https://physics.princeton.edu/pulsar/k1jt/wsjtx.html) successfully installed on one PC but not on my shack PC saying "Qt5core.dll" was missing. Version 1.6 installed on the shack PC fine earlier this year. I am no Windows expert and have not a clue what this is! BTW both PCs use Windows 10.
Does anyone know where I can get a free and virus free copy of this file please?
