I have a new PC and when attempting to install Start 10 on Windows 10, I get a greyed out area and it will not activate. I deactivated the machine, tried again, nothing. I can move around in the window but it doesn't activate. Some parts of the window work under Windows 7 but it still doesn't activate. Never had this problem before. I have installed, deactivated machines, etc. re-installed, etc. I even bought the program again and it does the same. Should I shut down all virus programs, etc. and try. I guess I  could. Just getting tired of doing the same thing over and over.  Any experts?

Thanks,
