Summary
Some customers are getting an "Unable to install the Apex One Security Agent. The system does not support SHA-2 code signing. Apply the latest Windows updates and try again" error message when trying to install Apex One agent on machines with supported legacy Windows OS.
Refer to the Apex One as a Service supported Windows Endpoint and Server platforms for more information.
Details
Customers who are still using legacy OS versions (Windows 7 SP1, Windows Embedded POSReady 7, and Windows Server 2008 R2 SP1) are required to have SHA-2 code signing support installed on their machines in order to successfully install or upgrade the Apex One Security Agent.
No customer action is required for Windows 8.x, Windows 10, Windows Server 2012 and above because the SHA-2 compatibility is already built-in.
