My version of CIC is not supported by current operating systems. What are my options to continue using it?
If there won't be any release available for current operating systems, then virtualization is the key. Virtualization allows you to run another version of Windows inside a Window. You can simply drag and drop the app from the main OS to the one virtualized and use it accordingly.
Give it a try using the following website: https://www.virtualbox.org/wiki/Downloads
Also check the documentation to learn how to create a virtual machine.
