RhinoPolyhedra plugin installation issue

Having trouble installing the RhinoPolyhedra plugin. The Rhino software is up to date, but getting the following error message when I try to install: “This package is not compatible with the Rhino Installer Engine. You may need to update to the latest Rhino Service Release to use this plugin.”
Also tried Control Panel > Programs and Features > Rhino 6 > Repair, and still getting the same error.

Hello - can you please run SystemInfo in Rhino and post(copy/paste) the results?

Sure - here it is:

Are you trying to install the current Rhino for Windows V6 version of RhinoPolyhedra and not the V5 version? https://www.food4rhino.com/app/rhinopolyhedra

Yes. The file I downloaded and tried to install is rhinopolyhedra60686315197.rhi

That file installed for me in Version 6 SR19 (6.19.19267.15571, 9/24/2019)

I downloaded the file, opened File Explorer, opened Rhino, and dragged the file into a Rhino vieport. Then clicked on the appropriate permissions requests.
Closed Rhino, reopened Rhino and PolyHedron was available.

How are you trying to install it?

Hey @elaverra, I suspect that the file associations for .rhi are incorrectly pointing to the V5 Rhino Installer Engine. Please try running RhiFix.exe, as described in the first section here:
