One of our customers had problems converting one of their documents to PDF through our service. Turns out they had links in the document which caused an exception to be thrown when the converter tried to turn the links into URIs, “Invalid URI: A Dos path must be rooted, for example, ‘c:’.”. I’ve attached a document which makes the Document.Save(Stream stream, SaveFormat saveFormat) function throw the exception, in Aspose.Words v188.8.131.52.
Thanks for your inquiry. After an initial test with Aspose.Words for .NET 14.10.0, I was unable to reproduce this exception on my side (please see attached out-14.10.0.pdf). I would suggest you please upgrade to the latest version of Aspose.Words. You can download it from the following link. I hope, this helps.
