For good measure, I just tested this on a fresh Windows XP SP3 install.
Thanks for your query. I have tested the scenario and have not managed to reproduce the same problem at my end. Please use the latest version of Aspose.Words for .NET 11.1.0.
The exception is handled internally by Aspose.Words.dll,
Thanks for sharing more information. I have tested the shared code at my end and have not found any problem. I have noticed that you are using Aspose.Words DLL for .net 2.0. Please set Target Framework to .net 2.0 of your project and execute the same code.
