I received the same error. I solved it with a fresh install of VSExpress 2013: - Download and install Visual Studio Express 2013 from here: [http://www.microsoft.com/en-us/download/details.aspx?id=40787](http://www.microsoft.com/en-us/download/details.aspx?id=40787) - Close and restart UE4 - Open and Build Project - Package Project for Windows This resulted in a successful build for me, hopefully it works for you. ---

I had a issue that took me days to find out. I found out just now! The problem for me was that some StaticMeshes/foliage was “not on the disk” So i had to delete all the trees and grass etc. And paint it all again… So if something is missing from the folder it was in when you put it in the level, it could crash on packing i guess.
