# License Key

## Evaluation license

If you began your evaluation after October 1, 2019 via the HOOPS Web Platform portal or self-assessment site:

- Your license key is automatically placed into the HOOPS Visualize Web installation directories, and you can find it here: /authoring/libsc/include/hoops_license.h
- You can generate your initial license key or access your existing key via the portal at https://manage.techsoft3d.com/

If your evaluation began prior to October 1, 2019 please go to https://developer.techsoft3d.com/license-generator/ and click “Generate Eval Key” to obtain your hoops_license.h file.

## Commercial license

Commercial developers who have licensed HOOPS Visualize Web should visit https://developer.techsoft3d.com/license-generator/ and click “Generate Full Key” to obtain a hoops_license.h file.

## Updating your license

After generating a new license, it is necessary to set it in the product. To do so, please do one of the following:

1. Run the installer again with the new license. This will place the license in /authoring/libsc/include/, and also copy it to several other locations for convenience to run the examples and tutorials.
2. Execute the license script at quick_start/update_license.sh or quick_start/update_license.bat with your license string as a command-line parameter:

    > update_license.bat 'your_license_string'

    $ update_license.bat your_license_string

    $ update_license.bat your_license_string

This will update all necessary files automatically.

3. Update the license string manually in the following files:

       // Update these files if you are still running through tutorials and examples
       ./quick_start/server_config.js
       ./quick_start/scripts/easy_convert.js
       ./authoring/converter/example/sample_batch_unix.xml
       ./authoring/converter/example/sample.sh
       ./authoring/libsc/java/examples/ScLicense.java

       // Update only these files if you have completed the tutorials and examples
       ./authoring/libsc/include/hoops_license.h
       ./server/node/Config.js
