Issue Details

When using the Import Web Service wizard, I get the following error message:

The following errors/warnings occurred when generating the local proxy dll and VI wrappers for this web service.
Internal Unknown Error.

Please contact National Instruments for help.

Can’t Create Project Library.

Project Library Generation Failed.

Possible Reasons:

1. The imported project library has a conflicting name with a project library already in memory.

2. The imported VIs have conflicting names with VIs already in memory.

The error is shown in the following image:



The following steps could help to solve this error:

  1. Close the project library and VIs and reimport the Web Service.
  2. Run LabVIEW as Administrator.

Additional Information

Important notes:

  • You must have the .NET Framework 4.0 installed to use the Import Web Service wizard.
  • You must provide a valid URL to a Web Service Description Language (WSDL), and the WSDL must validate correctly with ASP.NET. WSDL is an XML-formatted language used to describe a Web service and its functionality.
