Acrobat does not recognize DOCX files why?

[dianedoneit]

I am operating with Windows 7 operating system. There are .docx files created by someone else and I cannot get Acrobat to recognize the files in open or create a form. How do I fix this?

What version of Acrobat? What version of Office?

It's the latest version of Adobe Acrobat DC.

Unfortunately I do not know the version of office because I did not create them. Is their incompatibility with older versions?

Could be. How exactly are you trying to open the file? Are you just dragging and dropping it into Acrobat?
