Penguin installation scripting is similar to Rhino and Flamingo.
The format of the command line you would usually execute from a batch file (*.bat) is:
<path to installer .exe> <parameters>
The command-line parameters are:
/RhinoVer=[2|3|4] Specifies which version of Rhino to install for. This parameter is mandatory.
/CDKey=XXXXXXXXXXXX Use the 12-character Penguin CD-Key, without dashes and without the "PE10" characters. This parameter is mandatory unless you install Penguin as a workgroup node.
/WorkgroupNode=[Y|N] N means it's to be installed as a standalone and you'll need the CDKey parameter, Y means you want Penguin to get its license from the Zoo. This parameter is mandatory.
/Workspace=[Y|N] Should the Penguin toolbar be activated in Rhino or not.
/InstallPath=<full path to folder> Skip this parameter if you want to install it in the default folder ...Program Files\Rhinoceros\Plug-ins\Penguin
