Overview

When testing the AvaTax connection in Dynamics NAV we get the following error:

 

"This message is for C/AL programmers:

Cannot create an instance of the following .NET Framework object: assembly Avalara.AvaTax.Adapter, version=14.4.0.0, Culture=neutral, PublicKeyToken=..."

Environment

Resolution

  • Ensure that the Avalara dll is not in the C:\windows\assembly folder on the app server.
  • If it is there, then the Avalara objects need to be compiled. After compiling the objects you will be set.
