Error message: Null method parameter #4
When opening the SSIS+ License Application, you receive the following error.
Null method parameter #4
Make sure the SQL Server registry key for SSIS
is present for the version of SQL Server you are using. If it is not present, your SQL Server is not properly licensed or your SQL Server Integration Services (SSIS) engine/framework is not installed. To resolve this error, get a valid SQL Server license or correct your SQL Server Integration Services installation so that the SSIS framework/engine is present. The registry key from the chart
is associated, specifically, with the SSIS framework/engine.
Note that the installation of SSDT has nothing to do with the installation of SSIS. SSDT provides the tools to create SSIS packages, but does not install SSIS. The SSIS installation is associated with installation options set when SQL Server is installed.
