Cooking fails on Package/Launch. No Cook.txt file generated

Hi again,

This is less of a new problem and more of a continuation of an old issue with some new information. Just for clarity, I’m running the binary version of the editor, and I’m working on a BP only project.

Basically, my project is failing to package due to an AutomationTool issue that a lot of people seem to be having. I could get it to Launch when set to “Cook on the Fly” in the Project Launcher screen, but not when set to “Cook by the Book”. The output log says to look in “\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Unreal+Engine+4.5” for a Cook.txt but there is no such file in there.

I would have an easier time troubleshooting my issue if I were able to open the Cook.txt log after a failed build, but as it is, I’m a little lost for what to do next.

Edit: I’ve also just discovered that there’s no AutomationTool or AutomationToolLauncher folders in my /Engine/Source/Programs directory. Not sure it’s meant to be there in the binary version, but I’m on a fresh installation of 4.5.1, so either way I’m a little confused.
