Error upgrading project to 4.13

Hey everyone! I have a project I’ve been working on in UE 4.12.5, but I’m having trouble upgrading it to 4.13

This is the error I get:

106483-error.png

Then when I try to open it (it still makes a project file) I get this error:

106484-error2.png

And if I try to rebuild, I get this error:

106485-error3.png

Anyone have any ideas on how to fix this? Looks like it has to do with using steam…

Open your Game’s uproject file in a text editor. In your case, I believe this will be:

PROJECTROOT/PunchBomb/PunchBomb.uproject

Inside of that file, look for a “Plugins” JSON array. You’ll need to add the OnlineSubsysteamSteam plugin to this array. This will look something like this:

"Plugins": [
	{
		"Name": "OnlineSubsystem",
		"Enabled": true
	},
	{
		"Name": "OnlineSubsystemUtils",
		"Enabled": true
	},
	{
		"Name": "OnlineSubsystemSteam",
		"Enabled": true
	}
]

Hope that helps!

Thanks for the reply!

I ended up having to comment out all steam related stuff from my C++ documents and turn on the new steam online system plugin in 4.13 - problem solved!
