Action Center

Hello, I have windows 8.1 and the action center does not see avast free being installed. Is the program working?
would the paid version do this? I have tried all the fixes from this forum and no luck.
how can I tell the program is working if windows tells me different
any help would be great as I would like to use this program.
Thanks
