Exception while converting 2 MB Word Doc into PDF

Aspose.Words Product Family
1

I am trying to test your word to PDF conversion utility by modifying the comparison example you have given in github (GitHub - aspose-words/Aspose.Words-for-.NET: Aspose.Words for .NET examples, plugins and showcases).
But when converting a 2MB document I am getting an exception, the stacktrace of the exception is given below:

‘iisexpress.exe’ (CLR v4.0.30319: /LM/W3SVC/2/ROOT-1-131701726838046088): Loaded ‘C:\Windows\Microsoft.Net\assembly\GAC_MSIL\Microsoft.VisualStudio.Web.PageInspector.HtmlParser\v4.0_14.0.0.0__b03f5f7f11d50a3a\Microsoft.VisualStudio.Web.PageInspector.HtmlParser.dll’. Cannot find or open the PDB file.

Sorry for late response. Here is the document for which we are getting error.StudyProtocolTest.zip (1.3 MB)
