In Windows 10, I tried turning off Defender, downloading Claymore miner, unzipped it and ran it. I get this message: EthDcrMiner64.exe is not recognized as an internal or external command, operable program or batch file.

I switched over to Hive OS. Everything is okay until I get this red colored error message:

Network is off-line. Check your Internet connection.
Failed to start Walt for network to be configured.

I tried The card in the first three PCI slots and it just kept giving me that message in Hive OS.
