Hi,

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=1.0.0.0, 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 🙂
