You may get below error, when you try to import solution with Plug-in’s (or) registering a Plug-In using Plug-In registration tool

Action failed for assembly ‘assemblyname,Version=, Culture=neutral, PublicKeyToken=c79c3c28c5ba3ec0′: Assembly must be registered in isolation.

Reason :-

  • The User  who is trying to register is not a  “deployment administrator”

Fix :-

  • Add User as “deployment administrator” by following below steps
  • Open “Deployment Manager” tool
  • Under “administrator’s” tab, Right click and add current user
  • Reset IIS

Hope it Helps 🙂
