An issue I came over today. I tried to run my Portal 2 Authoring Tools, which I downloaded yesterday, but Steam says I need to intall it, and it doesn't work. When I go to my "Tools" tab, I can't find "Portal 2 Authoring Tools"! It's just gone.

I tried to restart Steam and my computer, didn't work, and yes, I do have Portal 2.

Maybe you can try to go to portal 2 -> properties -> local files -> verify integrity of the game?
IF there's something missing that might cause the sdk not to work properly. I'm absolutely not sure, but it's worth a shot

Thanks, but it doesn't work.
I've desided to re-install the game and would you believe it, my SDK gets installed with it.
Let's hope it works, though.

Go to your
C:\Program Files\Steam\steamapps\common or username (common= bought from retail) (username= bought online)\portal2\bin
And find SDKLauncher

Thanks
It says that editor/wireframe is missing, but I did a little search of the problem and I solved it.

Thanks again!
