Problem opening Rhino / Grasshopper model

[Elena9 (Elena)]

Dear Community, I have the following issues when trying to open (in Rhino 7) a Rhino + Grasshopper model created with Rhino 6.
I would like to know how to resolve this.
thanks in advance
Elena

1. Rhino Model opens fine

2. when opening Grasshopper i get GH loading errors: Object: SubBox (level 1)
   Ein Aufrufziel hat einen Ausnahmefehler verursacht.
   {TargetInvocationException}

Object: SubBox (level 2)
Die Datei oder Assembly “XformComponents, Version=1.0.0.0, Culture=neutral, PublicKeyToken=dda4f5ec2cd80803” oder eine Abhängigkeit davon wurde nicht gefunden. Das System kann die angegebene Datei nicht finden.
{FileNotFoundException}

3. when opening the grasshopper file itself it seems pufferfish is missing, error message:
   this file contains unknown objects
   round to decimal place / Pufferfish / 2.9.0.0. / Michael Pryor

4. when chosing download and install i get a package restore error:
   trying to download and install missing plugi-ns
   404: No package found by the name of ‘Pufferfish’.
   Failed to install the missing plug-in.
   Not all plug-ins were found on the package server.
   

   
   
   
   
   
   
   
   
   
   
   
   The missing plug-in(s) may be available at https://www.food4rhino.com.

So… then… why don’t you just install the plugin if it says this clearly that you are missing the plugin?

Alternatively you could:
-Search on food4rhino for pufferfish
-round to decimals by yourself, which is quite easy to do by native components
