We are not able to reproduce the mentioned "Can't open storage on LockBytes" exception issue on our side while converting word document stream data into PDF. We have attached sample which we have used to reproduce the mentioned exception issue on our end. Please do find the sample from the attachment. Try running the sample and let us know if this helps you.
If still you are able to reproduce this issue, kindly revert back us with the sample along with the template document which you have used to reproduce the issue on your end and it would be more helpful for us to analyze further on this issue.
Please let us know if you have any other questions.
On analyzing further on the attached document, we noticed that the document is MS Word pre - 97 format (File is created using older version of MS Word previous to 97 version). Currently DocIO doesn’t have support to preserve preformatted MS Word files. As a workaround kindly resave the document using any later version of MS Word and open that document using DocIO. For your reference we have attached the modified document which is resaved by MS Word. Please do find the modified document from attachment.
Please do find the compatibility with MS Word supported by DocIO from below link.
Still we are able to reproduce image alignment issue in Doc to PDF conversion. We have forwarded this to our developer for further analysis.
