Windows 10: Missing hosts when installing addon files for a certain app

Hi,I tried installing some effects and whatnot and the installer is called Red Giant trapcode, but when I open the installer this notification appears. Not really a tech person so I don't know how to fix this. Would appreciate some feedback on how I can fix this issue.Thanks

Hosts file editing

I have to jump in and say I use, and have used the host file for years. It's an easy way to take stress off of old name servers. I don't add everything, but major shares I do add to the host file. I've used the host file for some tunneling as well. I try to optimize my network as much as possible and I have a solid network. But Easy Rhino is right as well, you'll want to have everything he suggested as well. *Toast :toast:

 

How to change default app for file type

@Bree - yes, I'm quite aware of this thanks, but as you will see it's missing. I recall reading that clicking the dialogue at a certain point in blank space made it appear, and trying that once successfully, but doesn't seem to help now. Plenty of other similar reports of this option being missing.

List website to block in host file

So , recent I learn that I can block the ads on my pc if I put the ip address of that ads in the host file to go on 127.0.0.1, well I did not escape from all ads but I am not rely only on browser addons(take some work on cpu), also I like host idea because I can control it and block before enter on pc, not on browser, I put the list from here:
http://winhelp2002.mvps.org/hosts.txt
now I see another list who seems good too:
http://www.malwaredomainlist.com/hostslist/hosts.txt

I know this lists are not forever,I must check periodical for changes, but I want to know if are another, maybe, best list(updated periodical).

Look like the one from malwaredomainlist.com it is to aggressive, even yahoo messenger will not connect, so I will stay with http://winhelp2002.mvps.org/hosts.txt for now, maybe athers will post their finds.
