I'm trying to install the NodeJS runtime on the target machine, set an installer variable* from the output of a JS script using setInstallerVariableFromScriptOutput, then install more components that depend on the new variable.

How can I do this? I don't see an opportunity to run an Action after my NodeJS component installs, but before other components do.

  • This variable gets reused in a whole bunch of components and actions, so it does need to be set in a single central place

Hi spiffytech,

The action lists of each components are executed following the order that they are declared. So you can use the setInstallerVariableFromScriptOutput action in the first component and add a rule in those actions that you want to execute depending of the setInstallerVariableFromScriptOutput value.

Find more information about that in our User Guide: http://installbuilder.bitrock.com/docs/installbuilder-userguide.html#_main_project_and_components_execution_order

Also, another option could be putting the NodeJS in a separate component/folder, and in its readyToInstallActionList use the unpackDirectory to extract the NodeJS in a temporary folder (using ${system_temp_directory}), execute the setInstallerVariableFromScriptOutput, select/deselect the components depending of the output and finally delete those files extracted.

You can get more information in the link below: http://installbuilder.bitrock.com/docs/installbuilder-userguide.html#_unpacking_before_installation_time

Also, could you provide us with more information what you want to achieve?
