Building a Blueprint Project

I am trying to follow the steps in the build process document using UE4 4.1.9 and I keep getting these errors:

LogStreaming: Warning: Failed to read file ‘D:/Work/Test_Build/Releases/1/WindowsNoEditor/AssetRegistry.bin’ error.

I am even getting this error with a basic third person project??

Any ideas how to solve this issue?



Hello swhite68… for release your game you should install latest version of Visual Studio and make sure for selecting right choose for game engine when you install that.
after that make sure your blueprints compile without error … before releasing in unreal engine tabs select “File” then select “cook content for windows” … if you have error try for build for 32 or 64 bit … if you release your game just for windows go to “Project Setting” in left panel select “supported Platforms” and just select windows or anything you want … if you problem solve so good for you if not put “Output Log” here for helping better
good luck :):slight_smile:

H3KTOR thanks
So I need to have the source built in Visual Studio before I try to do a release build?
I thought it might be that :slight_smile:


if you mean “Engine Source” no you dont need to built you can download latest version in “Epic Launcher” … in another side you should install visual studio for releasing your game

H3KTOR thanks, I have Visual Studio installed but the licence wasn’t updated - I have since updated it and will go through your points and see what happens
Thanks for the help
