(Bug / Frozen) Preparing Plug-ins for First Use

Serengeti (Rhino WIP)

Please make “Preparing Plug-ins for First Use” smarter and optional !

from a user perspective:

Please:
An initial dialog - Do you want to load plugins from old rhino installations.

if yes - Allow users to select Plug-ins that should be loaded or not:
skip all
load all
load selected

from a developer perspective

rhino

I think the behaviour of “Preparing Plug-ins for First Use” must be very solid. (currently 31. July 2025) it is not)
This means, there should be a time-out mechanism if a plugin does not load, and the dialog should accept a ESC/Cancel.
Even if a plug-in stuck in un accessible dialog / commandline input or something else.
i am running into the same issue as described here:

sdk / rhinocommon

custom plugins should have a mechanism to only load on the rhino version they where compiled against / developed with.
Or have a property/function that returns the support RhinoVersion(s)
Or have a property that tells Rhino not to Auto-Load/Transfer on new installs / new Versions on the same machine.

I imagine that the plugin-class could have a very restrictive default implementation

public virtual bool AllowAutomaticFirstUseNewInstallations { get; set; } = false;

workaround ?

how can i stop “Preparing Plug-ins for First Use” ?

I have a few custom plugins that use an interactive licence mechanism “OnLoad”.
I do not want to mess up my Rhino 8 installation to be able to start testing WIP.
Start in safe mode failed ! on a fresh installation

thanks for some update regarding this.

Hi @Tom_P,

Plug-ins installed from the Package Manager or by dragging and dropping a .yak package are not automatically migrated.

Also, a plug-in’s OnLoad member can check the version of Rhino that is loading and refuse to load if needed by returning a value other than LoadReturnCode.Success.

I believe there is a special registry setting that will prevent plug-ins from being migrated. I’ll have to look into this more.
