Portal Pro is a set of test chambers focusing on solving puzzles locally rather than using complex fling techniques. The goal here is that the solutions are hard to come up with but easy to actually do.

Description

ATTENTION: This version of Portal Pro is out of date. Please download the latest version. This is the second release of this mod including several fixes. It is complete but still may contain some bugs or issues. Read details for installation and additional information.

I'm guessing you got the free version of Portal, and this error has to do with that. Try googling the error message to find a workaround. Or you can buy another Source Engine game to get access to the SDK which should let you install mods.

I have done everything that I need to do but I cannot see the mod in my games menu. My folder is D:\Steam\steamapps\sourcemods. If that will affect anything. Restarting the computer does not work either. I have also installed the 2007 and 2006 SDK bases. v1.1.1 does not not work either.

If you dropped the portal pro folder into sourcemods and restarted Steam, it should show up in your Steam library. Maybe you copied the contents of the portal pro folder rather than the folder itself? Your sourcemods folder should only have a folder called "portal pro" in it and nothing else (if you don't have any other source mods installed). For example, look for a file called "gameinfo.txt". The full path should be "D:\Steam\steamapps\sourcemods\portal pro\gameinfo.txt". If it's anything else or you renamed the folder, it won't work.

The "gameinfo.txt" is where it is supposed to be. However a lot of other mods I have used do not work either.

Make sure you have Portal 1 installed on the same drive (D). I think if it's installed in a different place (or not installed at all), Steam won't recognize the mod.

Portal is installed and on the same drive. I have the full version of Portal (just to clarify). So would there be any other problems.

I have got the mod working my games were installed under D:\Program Files (x86)\Steam\steamapps\common NOT D:\Steam\steamapps\common. So I moved the mod and now it works.
