Issue on library load with Spire.Doc 13.8

[nlekuona]

Using Spire.Doc trial 13.8.0 in Python 3.14, under Windows 11 Home, ver. 10.0.26100, trying the sample code in your wesite; when run, as soon as library is loaded either with

import spire.doc

or

from spire.doc import *

I get the following error:

NotImplementedError: There is currently no support for "spire.doc.DocumentProperty.DocumentProperty

This error happens only with Spire.Doc trial 13.8.0 loaded; same code with Spire.Doc.Free 12.12.0 loads library and runs correctly. The same code under MacOS 15.7 loads library with no issue (throws another error later when trying to set FontSize but I'll report that separately)

#Versions:

Spire.Doc trial 13.8.0
Python 3.14
Windows 11 Home 10.0.26100

Thanks for your feedback.

I have confirmed that this issue exists in Spire.Doc 13.8.0 and have already reported it to the development team for fixing. The issue ID is SPIREDOC-11594. This compatibility issue will be resolved in a future release, and I will notify you promptly once the updated version is available.

Apologize for the inconvenience caused.
