Houdini Indie subscription comes with a supplementary license which you can install on a second computer/laptop, or to work in dual boot mode. The use of these two licenses is restricted to a single artist, who can only use Houdini Indie on one of these computers at a time.

One set of licenses includes:

• 1 Renderer (Indie/Apprentice) - render using Mantra

If you are trying to license the secondary computer and you do not see any available licenses to install in the License Administrator, check the other computer already licensed with Indie. You may have installed both sets onto that machine.

You will need to return one set of licenses if all the Indie licenses are installed on one machine.

Returning a license will release it from the computer name and hardware. It will be placed back onto the account as a new license entitlement which can then be installed onto a new machine.

• Use the License Administrator (hkey) or sesictrl (non-graphical hkey).
• Returning licenses must be initiated by the computer itself.
• Licenses cannot be returned from the website.
• A license may be returned up to 10 times per year.

Returning licenses will release them from the computer name and hardware. They will be placed back into your SideFX licensing account as uninstalled entitlements which can be pulled down from another computer using the License Administrator.

When you return a license, a disable code is calculated and written to your licenses file on the computer.
The disable code is also recorded and added to your account. The License ID is then invalidated.

There are Two ways to return a license:

License Administrator (hkey):

1. Start License Administrator.
2. Select the License.
3. Right-click and select "Return License".
4. Enter your email address and the password used for licensing.

Non-graphical command line tool sesictrl

• The sesictrl program is a way to manage licenses without a graphical interface.
• To have access to sesictrl, you will need to setup the Houdini command line environment.

Once you have the Houdini environment setup in your Terminal, use sesictrl to return the license:

1. Run sesictrl print-license to get a list of installed licenses (the first column is the License ID).
2. Run sesictrl return-license License ID to initiate the return.
3. Enter your email address and password used for licensing.

Daily builds

SideFX provides new builds of Houdini almost every day. These daily builds contain bug fixes and small improvements to the software. The detailed list of fixes is available in the journal under the Support menu. By installing a daily build, users are often able to benefit right away from our agile development process.

Production builds

SideFX periodically designates a daily build of Houdini as a "production build". Production builds are released almost monthly and have gone through the full quality assurance process, so they are at least as stable as the original. It is thus advisable to upgrade from time to time, particularly from one production build to another to take full advantage of new improvements.

These are the most common issues with downloading, installing, or licensing Indie:

Can’t log into the website to download the software

• Trying to register your account and have not received an email, contact support@sidefx.com.
• Have an account and cannot log in, try resetting the password.

The license server is not running

• Indie must look to itself for licenses.

• Press the local server button. Ensure that it matches your computer name.

Stuck in the licensing loop

• Houdini Engine Indie will not run the Indie graphical interface. Verify that you have purchased Houdini Indie licenses.
• Ensure that any antivirus/security software on the computer is allowing communication between the client program HoudiniServer (hserver/hserver.exe) and HoudiniLicenseServer (sesinetd/sesinetd.exe).
• Modify the firewall to allow ports TCP 1714 (hserver client program) and TCP 1715 (sesinetd server program) locally.

Pop-up error warnings

Sometimes resetting your Houdini preferences will help resolve issues.

The most common pop-up errors:

SSL Error when trying to login using the License Administrator

• Windows 7: TLS 1.2 is not enabled by default. To enable will require a registry edit. Windows 7 is now unsupported for Houdini.
• Mac OSX High Sierra: Contact support for instructions on how to install a new system security certificate.

UnicodeDecodeError: 'ascii' codec

• Ensure your operating system is in English and that your username does not contain non-English characters or other symbols.
• Also ensure your folders containing any Houdini files do not contain non-English characters or other symbols.

Cannot save file

• For OSX Catalina users, navigate to System Preferences > Security and Privacy> Files and Folders.
• Ensure the folders you wish to save in are added and checked. This will give Houdini the appropriate permissions to save to those folders.

General Crashes

• Ensure your computer meets the System Requirements.
• Check your graphics card (and VRAM) against the System Requirements.
• Try upgrading your Houdini build to either the Production or Daily build
• Contact Support with the crash log, machine information, and license diagnostic files.

2. Under the View menu, select "Diagnostic Information".
3. Save the file.

You may also press the "Email License Diagnostic to Technical Support" button from the Server Information tab in the License Administrator. This will launch your email program with the diagnostic file.

Mac OSX

• On OSX crash logs are saved in /tmp.
