Cause

When a service starts, the service communicates to the Service Control Manager how long the service must have to start (the timeout period for the service). If the Service Control Manager does not receive a "service started" notice from the service within this timeout period, the Service Control Manager terminates the process that hosts the service. This timeout period is typically less than 30 seconds.

.NET Framework system requirements for Windows 8 and Windows Server 2012 Windows 8 and Windows Server 2012 install and enable by default the .NET Framework 4.5. However, the CEE Framework, "cava.exe", is a .NET Framework 3.5 service. You must enable .NET Framework 3.5. The Microsoft website contains instructions on enabling the .NET Framework 3.5 on Windows 8 and Windows 2012 at: http://msdn.microsoft.com/ens/library/hh506443.aspx

Resolution

Install or enable the .NET Framework 3.5 on Windows 10, Windows 8.1, and Windows 8
https://docs.microsoft.com/en-us/dotnet/framework/install/dotnet-35-windows-10

Once .NET Framework 3.5 is running and CAVA service started properly.
Data mover can detect CAVA server ok.
