If you want it for Plex Media Server, you need to install it all, and then remove app leaving drivers or Plex won't find the tuner since it is always used by the avermedia application.
Otherwise everything is good and straight forward.
I have had both Aver Media turners all have working good, your product is the 2nd one installed in HP desktop,
My 1st one installed long time ago in portable ASUS laptop.
