How to make package for windows?

So I am learning UE4, I want to make windows build just for test.

I opened project with just blank default project (just chairs exist) or 3rd person default project,

At menu-File-Package project-Window-64 , then choose folder.

But while progressing, log says it failed.

How should I do?

Thanks.

You’ll need to look at the packaging errors and find out what happened.
