Packagemanager installed Crane 2.0.4., but launch error?

I found something about .NET causing the error but switching to .NET framework does not seem to resolve the issue. Anyone has an idea what i can be? Im on rhino 8.34.

Path: C:\Users\KajX\AppData\Roaming\McNeel\Rhinoceros\packages\8.0\Crane\2.0.4\Crane.gha

Exception System.IO.FileNotFoundException:
Message: Could not load file or assembly ‘MathNet.Numerics, Version=5.0.0.0, Culture=neutral, PublicKeyToken=null’. The system cannot find the file specified.

Alright, I resolved it myself! The MathNet.Numerics.dll is missing from any version of 2.0x installation both through the Food4Rhino page and the Packagemanager. So instead i retrieved it from the 1.0 download on the Food4Rhino page and pasted it into the destination folder of the in my case 2.0.4. version of Crane.
