Gave a second try using the direct download link in yahoo email vs from here. The email link (same serial both places) worked when ran it (be sure program not running after installed, use task manager to end it). Only way for me to avoid failure messages like -1 Error Code and such trying to activate it. It will display the post installation of itself behind any active open window in front of the finished install screen.
PS the version from here showed in task manager as a 32 bit program, whereas it says here that 64 bit is needed. It’s version V 2.0 and task manager doesn’t have any 32 next to the .exe file so guess it’s 64 bit as supposed to be.
