Launcher Error

Failed to load the launcherDLL:

%1 not a valid Win32 Application

I’ll try uninstalling and reinstalling BMS, let you know if that fixes it

Edit: Did a clean install, still got the same error

Looks like broke the 2007 Base…again

Doubt they broke it again, mine boots up fine.
Does the clean install include the SDK Base?

Mine wasn’t. I got an error upon loading the game (and Source SDK Base 2007) from Steam:

CFileSystem_Steam::Init() failed: failed to find steam interface

So, I validated the Source SDK Base 2007 tool. It worked and I did a video stress test in Lost Coast (89FPS!) so I tried Black Mesa. It worked.

Try validating your Source SDK Base 2007 tool. (Library>Tools>Right-click SDK>Properties>Local Files>Verify Integrity of Tool Cache)

Agreed

Yup, validating fixed it

huzzah, now I can get back to murdering the textures

whoohoo

Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
