Can't convert a PDF into a Word doc using Acrobat X on Windows 10 PC

Hello, I have encountered this exact same problem. The Adobe Acrobat 10 Pro is pre installed in my laptop and I don't have the license number so reinstalling is out of question. Luckily I have stumbled upon the repair by chance. This solution is for you guys who also has the same problem. In my error it has been stated that there are three files that are problematic: DOCXFlt.flt, PdfFlt.flt, and RtfFlt.flt. So I go to the aforementioned folder which is C:\Program Files (x86)\Adobe\Acrobat 10.0\Acrobat\plug-ins\SafeAsNonPDF\Solid\ and moved those three files out of the folder (want to delete it at first but decided to only moved it just in case). Then I go to Control Panel --> Program and Features --> Adobe Acrobat X Pro, and clicking "Change" instead of uninstall, then I perform the "Repair" option in the Setup Wizard. After it finished, I tried converting my PDF again to Docx and it worked again just like before. I hope this fix is permanent so I don't have to repeat the process again.

Try running Acrobat X in a supported operating system, or use a supported version of Acrobat in Windows 10. The current version,DC,  is available by subscription including future updates.
