Can I work with older versions of Houdini?
Houdini is backwards compatible. Older versions of Houdini will run with the most recent license.
For example, if you have a Houdini 18.5 license, you will be able to open Houdini 18.5 and older (18.0, 17.5, 17.0 etc...).
- You need the latest License Server software and licenses to run both latest and older versions of Houdini.
- When installing older versions of Houdini, do not install the License Server component of the old version as it will overwrite the latest sesinetd binary.
- If you do overwrite the latest sesinetd server binary, reinstall the latest Houdini version again.
Old installers may be found on our public FTP server.
