Houdini is written for Windows and will run on any not too ancient Windows version. On Linux you can run Houdini using Wine without any significant performance loss.

 

You should have received the download link for the Houdini Setup, together with your Customer Code and Serial Number.

 

Download and run the Houdini Setup package. During installation you will be asked for the Customer Code and Serial Number.

 

The Houdini Setup will install the Houdini version that is appropriate for your 32-bit or 64-bit system. The 64-bit version is about 30% faster than the 32-bit version. On modern hardware the program will use the POPCNT instruction for another slight performance gain.

 

Each executable contains code for optimal execution from single-core up to 6 cores (for the standard Houdini version) or up to 32 cores (for the Houdini Pro version).
