Dynamics NAV 2013 R2 .DLL registration issues
Overview
NAV 2013 R2 objects have been imported and when compiled, objects are not recognizing the dll within the C:\windows\assembly folder
Environment
NAV 2013 R2 with Avalara AvaTax for Microsoft Dynamics NAV 2013 R2 - 7.10.35473.04.00 or Avalara AvaTax for Microsoft Dynamics NAV 2013 R2 - 7.10.35473.03.00. These two builds have dotnet instead of automation datatypes within the objects.
Resolution
1. Copy the avatax.avalara.adapter.dll from the C:\windows\program files (x86)\Avalara\... folder to C:\windows\assembly folder
2. Open a command prompt as administrator
3. Navigate to folder that has gacutil.exe and run "gacutil.exe -i C:\windows\assembly\avatax.avalara.adapter.dll " to register the dll within the assembly folder
4. Compile objects in NAV so objects can recognize registered dll
