--- Comment #2 from joaopa jeremielapuree@yahoo.fr --- The message in the console is pretty clear: 0024:err:module:import_dll Library packet.dll (which is needed by L"C:\Program Files\TP-Link\TP-Link PLC Utility\PLCOperation.dll") not found 0024:err:module:import_dll Library PLCOperation.dll (which is needed by L"C:\Program Files\TP-Link\TP-Link PLC Utility\tpPLC.exe") not found 0024:err:module:LdrInitializeThunk Importing dlls for L"C:\Program Files\TP-Link\TP-Link PLC Utility\tpPLC.exe" failed, status c0000135
Downloading and putting packet.dll in the system32 folder is enough to fix the bug.
I checked my real windows 10 box. This dll is not here. So I think the developper should have packaged this dll within his software.
