Windows 10.
(ASIO4All already installed and working correctly)
I tried double-click exe, command prompt window closed itself
opened cmd prompt manually and navigated to SJC200828 folder
entered soundjack.exe
got a list (21 lines) of qt.network.ssl: QSs1Socket: cannot resolve
ending with “ES: Failed creating websocket at port 1234
Most likely you have some kind of (software) firewall which blocks TCP port 1234 or you might have the tool “Manycam” installed. If so please deinstall it because SJ uses the same port as Manycam.
