Warning: Configuration Information Missing

Having worked with Valve’s Hammer Editor in the past, I recently decided to get back into the whole map-making vibe. Upon trying to launch the Hammer Editor from the Source SDK, I got hit with this error:

The configuration information for the game you're trying to edit is invalid or missing

Steam showing the following Warning dialog: “The configuration information for the game you’re trying to edit is invalid or missing.”

Strange. As you can see, I had the SDK configured like this:

Engine Version: The Orange Box

Current Game: Half-Life 2: Episode Two

I made sure my Half-Life 2 Episode Two download was complete before trying to open the Hammer Editor, so I was surprised when I encountered the warning. I immediately began to search for a solution online, and I found a few posts that recommended that I try running the “Refresh SDK Content” and “Reset Game Configurations” actions from the Source SDK Utilities menu:

"Refresh SDK Content" and "Reset Game Configurations"

“Refresh SDK Content” and “Reset Game Configurations” highlighted in the Source SDK list.

Unfortunately, this didn’t work for me.


It turned out all I needed to do was load the game at least once – as this would trigger the creation of the configuration information file required by the SDK.

In my case, the file itself was located here:

C:\Program Files\Steam\steamapps\your_username_here\half-life 2 episode two\ep2\GameInfo.txt

After I ran the game, that file was generated automatically, and I never saw the warning again.

    Did not help me, as I am a map maker and I have used Source SDK multiple times, and that doesn’t fix.
