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.

Solution

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.
