An odd problem here--I can launch Source SDK just fine, but hammer fails to launch when I click on the button. The Portal 2 Authoring tools works fine.

Launching faceposer or model viewer gives a "Unable to load manifest file 'scripts/game_sounds_manifest.txt'" error, and loading itemtest returns "cannot find the file specified."

Yes, I have verified the tool cache, restarted steam and my computer, and even reinstalled the SDK from scratch. Solutions from the Steam forums involving moving .cfg files around, reseting configurations and the like are equally ineffective, Hammer still won't launch.

Has anyone encountered this and knows a fix? Or can infer one based off of the errors?

I think you need to launch hammer directly from your common/game/bin folder.

Well, that worked. Thanks.

no probs

Yeah, they're sorta halfway through a mapping transition, and everything official for mapping is broken.

Though, then again, they're also halfway through phasing out full mod support for all of their games. :T
