Hi I installed the WSJT-X 2.6.0-rc1 version to give it a try. It worked with no problems until I tried to go back to the Version 2.5.4, 64-bit. It installed but would not run no mater what I tried (uninstall, removing all files from my computer that where left behind after uninstall, ran regedit to remove any ref to it) still it would not run Version 2.5.4, 64-bit. Had to reinstall WSJT-X 2.6.0-rc1 to get WSJT-X working again.
Computer Intel .7, 500gb ssd H/D, Windows10 Pro. HELP please.
