Howdy all,

I was just trying to package up my project for windows 64 and I got the following error. Anyone happen to know what it means? Any help is greatly greatly appreciated.

Hi lennysunreal,

The automation tool error from your logs is:

Program.Main: ERROR: AutomationTool terminated with exception: System.ArgumentException: An item with the same key has already been added.

This could be caused by a number of factors, here are a couple of AnwserHub posts with resolutions:

Unable to Package C++ Project for Win32/Win64

Program.Main: ERROR: An item with the same key has already been added

Let me know if neither of these apply to your issue. If not please add more information about your project:

  • Are you using the Binary (from Launcher) version of the Editor or working from Source (Github)
  • Is this a C++ project or Blueprints only
  • etc. (Any additional information you would consider relevant)

.

Thank you so very much :slight_smile: . I shall dig into this tonight.

Annnd sorry for the long delay on the reply. I worked on a bunch of other things before I got back to this. Anywhoozle. The first link you provided did the trick!

At one point my project was called ProtoTypeA. Becuase of that these files existed

Intermediate/protoTypeA.Target.cs

Binaries/protoTypeA.target

Then I changed my projects name to ProtoTypeB when I made a duplicate of it at one point. The I continued on working with ProtoTypeB. Becuase of that this files existed

Intermediate/protoTypeB.Target.cs

So! In order to get things to work again I deleted the first two ProtoTypeA files I listed above annnnnd Huuzzaaah :smiley:

Coompiled and working.

Thank you so very much :slight_smile:

Side note: If there was an error message that said. “Hey dummy! You got a duplicate file here that is causing errors, you should go delete it”

It would be awesome sauces :slight_smile:
