Portal: Prelude Forum

I'm having this same problem. I got the free version from the promo going on and beat the main game last night; then tried to install prelude today, exited steam, went back in, tried to play, and got an error telling me i needed a source game. =\

i wonder if the free version is somehow different from the "real" version and doesn't have certain necessary resources to count as a source base for mods?

Shit, that's the problem? I thought its because I didn't install it correctly, a friend told me to install sdkbase

Sorry for my english (Im from Argentina) but
I have a temporal form to play portal prelude in the free version of portal,
First install Portal Prelude in "C:\Archivos de programa\Steam\steamapps\steamuser\portal"
Second go to "C:\Archivos de programa\Steam\steamapps\steamuser\portal" and rename the folder "portal prelude" to "portalprelude"
Third open Steam and go to "Add Game", "Add an non steam game", and look for the "hl2.exe" in "C:\Archivos de programa\Steam\steamapps\steamuser\portal" and accept
Fourth go to the properties of your new game called "hl2" and in the box name put "Portal: Prelude" and in the target box put -game portalprelude
will be something like "C:\Archivos de programa\Steam\steamapps\july_mustang\portal\hl2.exe" -game portalprelude
close that window and play

I hope this be usefull

Thanks a lot. This should become sticky, as it solved the problem.

It hasn't solved the problem for me, I'm on a Mac, so I am not sure how I get to the hl2_osx.app. Any help?

We are not talking about the Mac version here.

but from were you are running portal prelude?
you got to add a non steam game and look for the hl2.exe

I just wanted to pop into here to tell that Portal: Prelude works for me with the free Portal version I downloaded yesterday from steam.

After having finished Portal quite quickly, I remembered that I've read about a mod for the game in GameStar magazine (from Germany) so I googled for that and got here. When I then arrived at the front page and read that my version of the game is problematic for the mod I was a little sad, but though tried the idea suggested here. So I installed the mod next to the original game (in "C:\Program files\Steam\steamapps\<steamuser>\portal") not renaming the folder and added this non-steam game to the list:

"C:\Program files\Steam\steamapps\<steamuser>\portal\hl2.exe" -game "portal prelude"

I've then started the game and it worked fine for me and I played till I got stuck at test chamber seven (Well, I need some sleep now).

At that point I want to thank the authors of this mod for their great work: Thanks a lot! This mod looks really great and even professionally made. So far it is as much fun to play as the original game even though it is a lot trickier at some points .

Apparently, this solution is illegal. Btw it also works with non-steam/illegal copies of portal (confirmed by a pirate-friend), which most likely points to the fact I am right.
