I created a Word document with some hyperlinks to PDF file, then I exported the Word file to PDF using the Acrobat DC component inside Word.
The links in the resulted PDF works well with Acrobat for macOS, it doesn't work with Acrobat DC on Windows. The links is broken if the target is a file with a name of 1 to 2 characters (es.: 0.pdf, 00.pdf).
It's very strange, it's hard to explain...
