The issue is customer is importing avalara objects into live database and cannot compile objects.
The environment is Microsoft Dynamics 2009 SP1
The resolution is customer did not run avalara executable which installs and registers the dll file. Customer downloaded zip file from admin console and ran the executable.
The cause is customer did not run executable in order to install and register the dll file. This causes a failure of the avalara objects within NAV to compile.
Note: AvaTax for Microsoft Dynamics NAV 2009 is sunsetted and no longer supported by Avalara as of April 30, 2016. This existing knowledge base documentation is available to provide known paths to resolution for documented issues. If you are using a version affected by service discontinuation and want to maintain access to Avalara Support, you’ll need to upgrade to the latest version of the integration as soon as possible
