Please note the error you are getting there is legitimate since Windows 10 is not a supported OS for CAD/CSD and even if you get the CAD running as mentioned by David, then also I am afraid that it will not be supported by TAC.

Windows 10 for CAD is not supported even on the 10.6(1) SU1 version and then from v11 it is all Finesse as you know that is completely web based and does not depend on the OS to that extent.
