Hi, I’ve been trying to package my project, but I keep getting an error. Only on this project.

“RunUAT.bat ERROR: AutomationTool was unable to run successfully.”

“BUILD FAILED”

“PackagingResults:Error: Error Unknown Error”

  • Windows 7 / 64bits.
  • Unreal Engine 4.10.
  • Blueprint Only.
  • Visual Studio 2015. (I tried to unistall/install nothing changed.)
  • I’m trying to package on Windows 64bits. (32bits don’t work either)
  • Build configuration : Shipping

I checked others posts but I can’t find anything to solve my problem.

Found a solution, I don’t know why It worked but heey, it’s working.

I deleted all folders in my project folder except :

  • Build
  • Config
  • Content
  • Intermediate
  • Saved

Tried to package project… Worked.
