When trying to start Failover Cluster manager you get an error message: “Microsoft Management Console has stopped working”
Inspection of the application event log reveals an error event id 1000, also known as an application error with the following text:
Faulting application name: mmc.exe, version: 6.3.9600.17415, time stamp: 0x54504e26
Faulting module name: clr.dll, version: 4.6.1055.0, time stamp: 0x563c12de
Exception code: 0xc0000409
As usual, this is a .NET Framework debacle. Remove KB 3102467 (Update for .NET Framwework 4.6.1), or wait for a fix.
