If Microsoft update KB3000850 is applied to Windows 8.1 or Server 2012 R2, the Netop Host process will not start.  This effects all versions of the Netop Host through the release of Netop Remote Control Host version 12.00.  A fix for this is included in the release of Host version 12.01.
To resolve this issue either remove this Optional Windows update or update/upgrade the Netop Remote Control Host to version 12.01 or newer.
