Change in Microsoft Windows certificates after January 1, 2016 causes issues for Windows 2008 R2 and Windows 7 systems upgrading to the latest CIC release/patch

The new Microsoft SHA-256 certificate affects Windows 2008 R2 and Windows 7 systems running Interactive Intelligence products that use the QoS driver, causing certificate errors after product installation and Windows Security messages. If you are upgrading to CIC 2016 R2 or later, CIC 2016 R1 Patch7 or later, CIC 2015 R4 Patch13 or later, or CIC 2015 R3 Patch19 or later, install Microsoft KB articles 3033929 and 2921916 (hotfix) before the CIC upgrade. 

If you are upgrading to CIC 2016 R3 or later, CIC 2016 R2 Patch4 or later, CIC 2016 R1 Patch10 or later, CIC 2015 R4 Patch16 or later, or CIC 2015 R3 Patch21 or later: 1) Install.exe now detects if the two Microsoft KB’s are not installed and 2) A public property has been added for group policy deployments of products that do not use the QoS driver.
