Missing Grasshopper Files on my install - Help!

Grasshopper

Hi McNeel team @wim @pascal,

I’m running Rhino 7 SR38 (64-bit) and I’ve noticed that my Grasshopper installation is missing the SubD components — specifically SubD.gha and SubD.dll.
As a result, I can’t access key tools like Multipipe or the Size (SubD) component in Grasshopper.

Could you please provide the official SR38 versions of these two files so I can restore them manually to:

C:\Program Files\Rhino 7\Plug-ins\Grasshopper\Components\

I’d prefer not to do a full repair install since my V-Ray environment is stable, so a direct link or zip package would be ideal.

Thank you very much for your help,
Jake Oliveira

Hi Wim, thanks for the quick reply! I sent this to the support email, just sent it to the tech email. I am working towards a deadline and panicking because I really need to get my grasshopper definition working.

This could be a conflict of some sort with a 3rd party plugin. Try starting grasshopper via the command line with GrasshopperLoadOneByOne and say no to 3rd party plugins.

Hi @japhy , I just tried your suggestion, no success. A past tech support colleague set up my Rhinoceros and the only components that show in Grasshopper for me are shown in the attached image.

Thanks all for your help!!

Hi Jake -
This is what is in that folder on my system:

As far as I can tell, the SubD.gha and SubD.dll files are not on this system.

Hey @wim , thanks for the reply. It seems the Multipipe component in Grasshopper and the SizePoints input only actually function with that .gha and .dll - So i am a bit confused. Is there any way to get those files? I really appreciate you aiding in this.
