PDF to DOCX .NET conversion not produce output

Hi,
I made an application that get a PDF as a input and convert it in a DOCX document.
The problem is when I use a PDF with a lot of pages, the application on save go in loop and seems never stop (I waited for 10 minutes and the process continue).
I use this code:

DocSaveOptions saveOptions = new DocSaveOptions();
saveOptions.Mode = DocSaveOptions.RecognitionMode.Flow;
saveOptions.Format = DocSaveOptions.DocFormat.DocX;
this.Pdf.Save(path, saveOptions);

I know, the pages of PDF are 276 but I don’t expect the conversion to take a few seconds, but I don’t expect that after ten minutes, not only is it not ready, it takes even longer.

I tried also to split in two part the PDF, and take the first PDF made of 138 page. The result is the same.

I also tried to split another time and take the first PDF made of 69 page. Always the same.

Can you help me?
Thank you.

Thank you, this is the PDF with 276 pages.

I let the conversion run, it didn’t stay in the loop, but it took about 10 minutes.
It is normal or there is a way to make the same conversion in a fast way?

I request you to upgrade to latest version because it is converted to DOCX within a couple of minutes. coppie arbitrali 2017-20181.docx (2.1 MB)
