Hello everyone,

The Heteroptera plugin Version 8.0.4 and Version 8.1.5 both can’t loaded on my computer, I have install it several times from PackageManager, but it keep throw an error:

An error occured during GHA assembly loading:
Path: C:\Users\hx.li\AppData\Roaming\McNeel\Rhinoceros\packages\8.0\Heteroptera\8.1.5\Heteroptera.gha
Exception System.IO.FileNotFoundException:

Hi HazeLi -

You should probably be running Rhino in the standard .NET Core.
-wim

Many other plugins(Including the plugins I developed myself) in my GH files use the .NET Framework. If I switch to .NET Core, it might cause many other plugins to stop working… I’ll try it, or maybe I should think of another solution… Thank you :sparkling_heart: .
