Hi! 🙂 I spent the whole day today trying to figure this out

Just FYI, I downloaded the game from MEGA and followed the steps from “How to play on Windows – Method 2”. It worked, but the game was soooo laggy.

I’m not 100% sure this will work for everyone, but you can try going to the game’s folder, for example:

C:\Program Files (x86)\EA Games\Harry Potter and the Chamber of Secrets\system

Then replace the content of your default.ini file with the following:

I hope it works for you too! 🙂

change the color bit to 64 bit. it will work smoothly

which one is for hp3?

Like Harry Potter 1, I looked up JokerAlex21’s video on how to make this game work. You have to look up “Harry Potter Chamber of Secrets PC no-CD crack”, and find a legitimate one. Here’s the link for an internet archive collection, containing ones for several Harry Potter games, as of 10/3/2025:
https://archive.org/details/harry-potter-pc-games-no-cd-cracks
You have to go to “Download Options” on right side of page, click on the “Windows Executable” option, and choose “Game.exe” – this is the one for Chamber of Secrets, for some reason.

Once it’s downloaded, you copy and paste it into the “system” folder of the Chamber of Secrets you downloaded here, and choose yes when it asks about replacing the Game.exe already there.

I’m not seeing any folders in the downloaded files called “system”.

Hi Timbo! You need to “unzip” the 7zip file in order to access the game files. Hope this helps!

Happy Gaming!
