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:
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:
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.
