Then it should be "...\Introversion\Prison Architect" folder instead of "C:\ProgramFiles(x86)\Steam\steamapps\common\Prison Architect" folder, i believe.

It seems like all of my mods are downloaded in /Introversion instead of the steamapps/common location. I've gone through all the files and can't locate the .mod file. Can anyone help me make this mod work?

I dont know what is a GoG version. I did that and works without having to activate the mod. Just by having the data folder in main game folder. Thanks.

If you're running the Steam version of the game, you need to find the .mod file that was downloaded to it when you subscribed to the mod. Open that file with WinRar or 7-Zip.
Now, navigate to C:\ProgramFiles(x86)\Steam\steamapps\common\Prison Architect\, create a data folder there, and extract the reform_programs.txt into it.
You subscribe to the mod so that it shows up for activation in the game (under Extras > Mods), then copy that text file into a folder called "data" in the root of the game directory so that it can actually run the mod code.
Don't know why it has to run that way, but then again, I'm running a GoG version of the game, not Steam.

Still working? Anyone?

Where is the reform_programs.txt file?

I noticed that once I activate the mod it seems to make it so prisoners don't go to certain programs

There is no reform_program text file anywhere

@Urbanvixen: You have to create the 'data' folder inside C:\ProgramFiles(x86)\Steam\steamapps\common\Prison Architect. After you did it, put the 'reform_programs.txt' inside the 'data' folder. Also, remember to restart the game. I am not sure why the original reform programs can't be modded in the traditional way.

Doesn't seem to work. And I don't have a Prison Architect\data folder.... Any ideas ?

I've been waiting for a mod like this. Thank you!
