We're investigating the issue and will let you know about the resolution, the earliest possible.

We appreciate your patience.



I have tested the issue at my end, and have successfully converted both files to pdf.

I used Apose.Pdf, and Aspose.Words Please download latest versions of both and try at your end. If problem still persists then please do let us know.


Thank you!
I’ll try and let you know results.

Everything is fine now!
Thanks a lot !
