Download and Evaluate Houdini MC


No matter how big is your Escape Room, there’s something new for you in the latest release of Houdini MC.


Houdini MC is an ongoing project. Frequently, we release a fresh version considering our customer’s suggestions and requirements. We’re constantly listening to our customers’ feedback, wrestling with how to implement specific ideas, and prioritizing what will help escape room owners the most.


Instructions on how to install Houdini MC

Step 1: Click on the “Download the latest stable version” button below to download the Houdini.zip file.

Step 2: Then extract the contained files to a directory. Please make sure that the size of the downloaded file is 126,093,922 bytes. If you don’t know how to extract files, kindly refer to this tutorial.

Step 3: Double Click on HoudiniInstaller.exe.

Step 4: Select “Clean Install” and press “Next”.

Step 5: Wait for a few moments and click on “Launch Application“. Windows will ask you TWICE to access the file’s execution during the first execution. The first prompt is about the IIS Express Server, and the second one is about Houdini MC. Click and uncheck the  “Always ask before operating this file” and click on “Run“.


I just want a stable solution. I don’t need all these new features 🙁

“I want it all! All the features!
All the work!” And I want them now. I can’t wait for an official release.

Change Log:

You can use this list to track the completed tasks or even the used clues. Use the room editor to add these steps and the main console to monitor them. Please check the updated Room-Editor tutorial for more details.
  2. Custom Actions: Significantly improved performance on custom actions. Check the updated Custom-Actions tutorial for more details.
