I cannot open *.p65 file(s) in Adobe InDesign (version 17.2 x64) that's installed on Windows 10. Any suggestions on how to open *.P65 File in InDesign, Any Plug-in Required? Also, How to convert *.P65 File into a PDF file?

.P65 is an older version of Page Maker, which seems to be replaced by InDesign. Yesterday, I installed Indesign but sadly, I cannot open that file.

Kindly suggest. Thank you in advance.
