UE4 Windows build blocked by antyvirus software

I’m building a game for PC, and have sent the PC build I made to some frieds to show them the progress. I already got few feedbacks that the build is being BLOCKED by antivirus software and firewalls as well.

If I publish a paid game to people and tens of % of players will have this issue, then this will be z PR Suicide.

PLEASE SOMEONE INVESTIGATE THIS ISSUE. IF YOU ARE HAVING THE SAME PROBLEM - COMMENT ON THIS THREAD.

If you want to ship a game, use an installer. There are many to choose from.

If you don’t provide an installer then Windows won’t know that the game is safe. When you copy anything without installing it, the DLL files will be “blocked”. Your friends can go through the package and unblock all the DLLs – or there is a script somewhere that will unblock all DLLs in a directory tree. Try this Unblocking files from folders and sub-folders – Mohd Aslam's Blog.

But if you want to look professional, you will have your game installed via an installer.

If it’s networked then the correct ports need to be open. I’m not sure how that is unreasonable since the alternative is to make your PC unsafe. This is a problem for many games, though. Lots of gamers have to open ports all the time to get games to work. But again, try to do it from the installer.

I’ll try that. Thank You. I hope this and signing the app will help, but I’ve read threads describig situations where indie developers had similar issues even when releasing on steam.

You might want to have a friend try unblocking DLLs in the meantime, or try it yourself on another machine. See if that helps. I’ve definitely had to walk friends through that process when I’ve shared things, UE4 and otherwise.
