Add-Type -AssemblyName Microsoft.SqlServer.Smo Doesn't Work
Add-Type -AssemblyName Microsoft.SqlServer.Smo only works if you have an older version of SQL Server installed.
Add-Type : Could not load file or assembly 'Microsoft.SqlServer.Smo, Version=22.214.171.124, Culture=neutral,
PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
Please update the version table to support all versions of SQL Server, including 2016, if possible.
