Hi,

Thanks for your message.
Kindly note that our product is based on the Microsoft Word standard. There is an error message displayed even directly opening your document by Microsoft Word. You can verify this on your side. Thus, please ensure the correctness of the document itself.

Hi,

Thanks for your response Herman. Yes, Microsoft Word 2019 and above display a warning message - that the Custom XML cannot be saved in the current format - but it still opens the document and you can view it. Spire.Doc just throws an exception and does not open the document.

We are requesting that Spire.Doc opens the document with a warning message just like Microsoft Word.

Thank you!
