Nastily, Microsoft Defender flagged KCC_7.3.0.exe as being infected. I ran it in a sandbox and nothing showed up so I set Windows Defender to allow the file. Oddly using VirusTotal, both Microsoft and SecureAge found KCC_7.3.0.exe to be infected while neither detected any issues with KCC_c2e_7.3.0.exe & KCC_c2p_7.3.0.exe.

Edit: Equally oddly when I built KCC locally, Windows did not gripe about it.
