I would contact Support directly for this. You can use this link:
Question:
What are you trying to achieve with examining the PDFs? Is it REQUIRED as part of your test to open the PDF in Adobe Acrobat DC? Or is it that another application is generating the PDF's and you're doing some sort of validation of the contents?
If it's the later, there's a tool that you can use called PDFBox which has documented usage within TestComplete to allow you to compare and validate PDF contents.
