Acrobat won't open my files- Windows 10 Acrobat XI Pro

[SMolsbee1969]

When trying to open the majority of PDFs recently I get the below message. It was working fine until I got a message not long ago that said support was discontinued or something to that effect. Any help is greatly appreciated. I just want to fix the issue so I can open files.

Opening non-PDF files in Acrobat requires them to be converted via the associated application, which is done via the OS. Since Acrobat XI is quite an old version, not officially compatible with Windows 10, it's not surprising that such connections are malfunctioning. You need to convert the file directly from Word (via the Adobe PDF printer, as mentioned in the error message, or the Acrobat plugin, if it works), and then you should be able to open the resulting PDF file in Acrobat.

It has been opening files just fine until the last week or so. The files
were originally PDF.
I'm wanting to find out how to fix this so that I don't have to convert
100's of documents individually.
