Shotgun Launch Nuke Non-Commercial, other than licensed Nuke. Is there a way we could force Shotgun to Launch licensed Nuke or Nuke X instead of picking up the Non-Commercial all the time ? Reason for failure: A suitable license does not exist. ## RLM LICENSE DIAGNOSTICS nuke\_i : No license for product (-1) License Path: C:\Users[username]\FoundryLicensing\04d9f504cd4c;C:\Program Files\The Foundry\RLM;C:\ProgramData\The Foundry\RLM;C:\Program Files (x86)\The Foundry\RLM;C:\Users\he.sun\FoundryLicensing;C:\ProgramData\The Foundry\RLM ---

Hello – I’m not an expert in Nuke license issues, but I wonder if maybe you can set the `FOUNDRY_LICENSE_FILE` environment variable to point to the license file that you want to use? [(More info in Foundry’s documentation.)](https://learn.foundry.com/nuke/8.0/content/user_guide/configuring_nuke/nuke_environment_variables.html) You could set this variable in the `before_app_launch` core hook, which runs right before Nuke is launched. ---

If you have a physical license file that you want to point to than what @tannaz said is exactly what you want. However if you have a server that is hosting the license, and you have multiple floating licenses, than you want to look into pointing the ‘foundry\_LICENSE’ environment variable to port@server. This can be done during a startup script when a user logs in, or part of a setEnv phase called from a launcher script, or the before\_app\_launch if you are always inside a shotgun environment… there’s many ways to handle this just depends how your place of work is setup. ---

OK. We have floating license, so need to set env port@server. Can you be more specific about step to set it up please ? where is `before_app_launch` core hook located for example ---

the before\_app\_launch hook is located in the tk-multi-launchapp shotgun app, I have no idea how your shotgun config is setup… but generally speaking… you will have a shotgun project with the following folders inside cache, config, install… if you don’t have a central install for all your apps also known as a shared\_install which is no longer the default then your current shotgun installed apps will be located inside the “install” folder. go inside that folder, and double click on “tk-multi-launchapp”, inside there you will see a version folder (the current installed version), inside that folder you will see a “hooks” folder, go in there and you will see “before\_app\_launch” DONT EDIT THAT .py FILE! so… thats where its located… but now you need to make a lot of decisions…I strongly suggest you start reading: [Administrating Hooks](https://support.shotgunsoftware.com/hc/en-us/articles/219033178-Administering-Toolkit#App%20level%20hooks) [tk-multi-launchapp](https://github.com/shotgunsoftware/tk-multi-launchapp/wiki/Documentation) There are several embedded links on that page that also highlight hook editing, and managing your project configs. The general goal is you will copy that before\_launch\_app hook into your project “@configRoot/configs/hooks/” under a “tk-multi-launchapp” that will need to be created, then inside “@configRoot/env/includes” you will see a “app\_launchers\_yml” inside there you can define the new location for your “before\_launch\_app” hook for each piece of software you want to set ENV variables for. If you are using the new config\_default2 it looks like these hook locations are set inside “@configRoot/env/includes/settings” and then there will be a “.yml” called “tk-multi-launchapp.yml” [ConfigDefault2](https://github.com/shotgunsoftware/tk-config-default2/tree/master/env/includes/settings) Example from config\_default: app\_launchers\_yml: These are what the settings look like by default. launch\_maya: defer\_keyword: ‘’ engine: tk-maya extra: {} hook\_app\_launch: default hook\_before\_app\_launch: default icon: ‘{target\_engine}/icon\_256.png’ linux\_args: ‘’ linux\_path: ‘@maya\_linux’ location: version: v0.7.6 type: app\_store name: tk-multi-launchapp mac\_args: ‘’ mac\_path: ‘@maya\_mac’ menu\_name: Launch Maya 2015 versions: windows\_args: ‘’ windows\_path: ‘@maya\_windows’ you want to change hook\_before\_app\_launch: default to: assuming you have put the new before\_launch\_app.py into “@configRoot/hooks/tk-multi-launchapp” “{config}/tk-multi-launchapp/before\_app\_launch.py” Hope this helps… It’s a lot of information…anyone that has more info, feel free to add on :D; -Ross
