Retrieving the COM class factory for component with CLSID - Using PDFCreatorLib

I'm working on a web application that is built in a .NET MVC Framework. When testing I've encountered this error. The page converts data into a PDF File.

It's failing on this code.

private static PDFCreatorPilotLib.PDFDocument4 SetUpPDF(string title)
{

    PDFCreatorPilotLib.PDFDocument4 PDF = new PDFCreatorPilotLib.PDFDocument4();
    PDF.SetLicenseData("InsolvencyService", "Z5S9H-9AVVA-F84XV-9LQ4N");
    PDF.SetTitle(title, fontCharset.fcANSI);
    PDF.ProducePDFA = false;
    PDF.Compression = compressionType.coFlate;
    return PDF;
}

The full error is Retrieving the COM class factory for component with CLSID {465FE951-D267-4D90-A019-7994822E137E} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)). Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
