You may install, use, access, display and run one copy of the Product on a single computer, such as a workstation, terminal or other device (“Workstation Computer”). The Product may not be used by more than two (2) processors at any one time on any single Workstation Computer.
First of all, for me 'two processors' at one time means, two physical processors (not one processor with multiple cores), secondly, you are using it on the same 'single' computer, and at any one given time, only one 'instance' of the OS can be used by you, hence as long as you stay within these limits I think it would be ok.
