CA Spectrum install has a host evaluation screen that fails if the OS is Windows 2016.
Is CA Spectrum supported on Windows 2106
Windows 2016 is not supported until CA Spectrum 10.3 is released. If you attempt to install CA Spectrum 10.2 (or prior) on Windows 2016 the install will fail at the Host Evaluation screen.
You need to either wait for CA Spectrum release 10.3 or use another install with Windows 2012 installed.
