It turned out I shouldn't have put it in C:, but in Users.

Uhm, it doesn't go in either of those places. The mod folder should be at:

C:\Program Files\Steam\steamapps\sourcemods\

If that didn't work for you, putting it in Users will work less.

Did you restart steam after putting it in the sourcemods folder?

I finally got it to download, but nonetheless it was pretty frustrating. Hopefully Moddb can host the installer in the future.

wouldn't know, but it's the same updated version released yesterday, if you didn't download that one you may give this one a shot, I don't think it does fix anything related to Mr. Whirly though.

OK so we shouldn't use this file then?

nope, I created it for the people that were having issues having it showing up on steam(it seems there are at least 2 possible sourcemods folders, the installer should automatically pick the right one for those people)

And what if it doesn't?

Edit: Then you don't have Episode 2. Doi.

DuckSauce - I registered just so I could post here and thank you for this great mod. I thoroughly enjoyed it. I did find one place where I unintentionally bypassed one of your puzzles. Would you like me to post the information here, or how can I get in touch with you? I don't think this forum has a PM feature.
