Microsoft .NET Framework 4.5.2 Requirement

Starting in CIC 2016 R1, .NET Framework version 4.5.2 is required on the IC server and client workstations that run IC User Applications and IC Server Manager Applications. Microsoft .NET Framework 4.5.2 is a highly compatible, in-place update to .NET Framework versions 4.5.1, 4.5, and 4.0.

For more information, see the Microsoft KB article https://support.microsoft.com/en-us/kb/2934520. If .NET Framework version 4.5.2 has not already been installed via Windows Update, install it on the IC server from the CIC 2016 R1 or later .iso file and on the client workstations from the IC_WorkstationPreReqs share on the 2016 R1 IC server. For details, see System Software Requirements.
