"The customization assembly could not be found or could not be loaded.”

Question

Hello,

I'm using VSTO 2010 and created a Word 2010 Template project as follows (dev machine with Windows Server 2008 R2, Office 2010, VSTO 2010):

Create New C# Project > Office > 2010 > Word 2010 Template

Attach the following code to the Document New event:

        private void ThisDocument_New()

        {

            object fixedFormatExtClassPtr = null;

            this.ExportAsFixedFormat(@"C:\temp\MyDocument.PDF", Word.WdExportFormat.wdExportFormatPDF, false, 0, 0, 0, 0, 0, false, false, 0, false, false, false, ref fixedFormatExtClassPtr);

        }

Hit F5. The following exception will be displayed:

    “The customization assembly could not be found or could not be loaded.”

The same behavior occurs when executing many other lines of code.

Any ideas?

Regards,

António Ribeiro

Hi Antonio,

Thank you for posting in the MSDN Forum.

You can change

object fixedFormatExtClassPtr =  null;

into

object fixedFormatExtClassPtr = System.Type.Missing;

Besides, you'll need to make sure that you have access into C:\temp.

Best regards,
